Bosch Washing Machine Error Codes Explained for Aylesbury Rental Properties

Published October 2026 | Bosch Washing Machine Error Codes Explained

Landlord Obligations Under Current Regulations

When a landlord includes a washing machine in a furnished or part-furnished tenancy, they take on a duty of care for that appliance. Under the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018, landlords must keep rental properties in a condition fit to live in. Washing machines aren't explicitly named in the legislation, but case law and guidance from Shelter consistently hold that appliances listed in the tenancy agreement must be kept in working order.

For landlords in Aylesbury, this means responding promptly when a tenant reports an error code on their Bosch machine. Leaving a tenant without a working appliance for weeks while you shop around for the cheapest quote isn't acceptable under current standards, and can result in a formal complaint to Buckinghamshire Council's housing team, or action through the Property Redress Scheme.

Bosch machines are built well, but when a fault code appears on the display - E18 for a drain fault, E17 for a water inlet problem, F34 for a door latch failure - that's the machine refusing to continue until the fault is fixed. These codes each point to a specific system failure, and landlords who dismiss them as the tenant pressing the wrong buttons typically end up paying for a more expensive repair later, because the underlying fault worsens when the machine is run through failing cycles repeatedly.

Landlords also have obligations under the Electrical Equipment (Safety) Regulations 2016 to ensure appliances they supply are safe at the start of the tenancy. This doesn't mean a PAT test is required every year in all cases, but the appliance must be in safe working order when the tenancy begins. If the machine is more than ten years old and showing recurring fault codes, a landlord would be well-advised to replace it rather than patch it repeatedly.

What Tenants Are Expected to Handle

Not every Bosch error code means the landlord needs to call out an engineer. Some faults are triggered by user-controllable factors, and tenants are reasonably expected to deal with these themselves before reporting a fault.

The most common tenant-side issue our engineers encounter is the E18 or E23 drain fault caused by a blocked pump filter. Bosch machines have a pump filter behind a small access panel at the bottom front of the machine, and if it's packed with fluff, coins, hair grips, or debris, the machine can't drain and throws a fault code. Clearing the filter takes around five minutes and costs nothing. If a tenant reports an E18 and the filter hasn't been touched in months, a landlord would typically be within their rights to pass the call-out charge back to the tenant, provided this is clearly set out in the tenancy agreement or accompanying documentation.

Other areas where tenants carry responsibility include:

• Not overloading the drum, which can trigger motor-related codes such as F43 or contribute to bearing wear
• Using the correct detergent type and amount - excess foam causes pressure sensor errors that can look like mechanical faults
• Keeping the drain hose clear of kinks and ensuring the waste outlet isn't blocked
• Reporting faults promptly rather than running the machine repeatedly through failing cycles

That last point matters more than people realise. Running a Bosch machine through ten failed wash attempts while it's displaying an active fault code can turn a 120-pound drain pump repair into a 350-pound PCB replacement. Tenants who delay reporting and then continue using a faulty machine complicate any later dispute about who bears the cost.

Grey Areas - Where Disputes Happen

The difficult territory in rental appliance disputes tends to fall into three categories, and Bosch error codes are no exception.

The first is wear and tear versus misuse. A drum bearing that's worn out after eight years of daily use is wear and tear - the landlord's responsibility. A drum that's been damaged because the tenant regularly ran it at full capacity with heavy loads is misuse - potentially the tenant's cost. The problem is that Bosch's fault codes don't make this distinction. An F43 code, which signals that the drum isn't turning, can result from a failed motor, a snapped belt, or years of overloading. Without an engineer's written assessment, it's very difficult to attribute the fault from the code alone, and this is where disputes in Aylesbury rental properties tend to get stuck.

The second grey area is delayed reporting. If a tenant spots an E17 water inlet fault, doesn't report it for three weeks, and continues using the machine daily while the intermittent fault develops into a failed inlet valve or a damaged pressure sensor, apportioning the blame becomes complicated. Both parties have responsibilities here - tenants must report promptly, and landlords must act on reports promptly.

The third area involves appliances that are in the property but not formally listed on the tenancy agreement. This is surprisingly common in Aylesbury properties that have changed tenants several times. If a Bosch machine was left behind by a previous tenant and the landlord neither removed it nor formally included it in the agreement, the legal position on who maintains it sits in murky territory. Our advice to landlords is simple: if it's in the property when a new tenant moves in, either remove it or add it to the inventory with clear notes on its condition.

How to Report This Issue (Tenant Perspective)

If your Bosch washing machine is showing an error code and you're renting, here's how to handle it in a way that protects you and gets things moving quickly.

1. Note the exact error code. Write it down or photograph the display immediately. Bosch error codes are specific to particular system failures - E18 means something different to F34, and that precision matters when your landlord is booking an engineer.
2. Check the basics first. Clear the pump filter if you can access it safely. Check that the water supply tap behind the machine is fully open. Make sure the door is closing and latching correctly. If the fault clears, report it anyway so there's a record of it happening.
3. Report in writing. A text message works but an email creates a clearer timestamp. If your landlord uses a property management platform, log it there. Include the specific error code, when it first appeared, and what you've already checked.
4. State a reasonable expectation. You don't need to be aggressive about it, but including a line like "could you please confirm when an engineer can visit" sets expectations and starts the clock. For a family home, waiting more than five working days for a response would typically be considered unreasonable.
5. Escalate if needed. If you're not getting a response within a reasonable timeframe, you can contact Buckinghamshire Council's private housing team. Keep copies of everything you've sent and received.

You can also run the error code through Voltrade's GoFIX diagnostic tool before you report. It gives you a plain-English explanation of what the fault code means, which helps you describe the problem accurately to your landlord and speeds up getting the right engineer booked rather than a general call-out.

Getting It Fixed Quickly in Aylesbury Rental Properties

Speed matters with appliance faults in rental properties. A family without a working washing machine in Aylesbury isn't going to sit patiently while a landlord takes two weeks to arrange a repair. When the process works well, it looks like this: the landlord contacts an engineer within 24-48 hours of receiving the fault report, the engineer visits for a diagnostic check, and parts are ordered and fitted within a few days for common Bosch spares.

In Aylesbury and across Buckinghamshire, there are engineers who work regularly on Bosch machines alongside other major brands including Samsung, LG, Hotpoint, and Beko. A diagnostic visit typically costs between 60 and 90 pounds, covers 30-60 minutes of assessment, and should result in a written report confirming the fault code, its cause, and the recommended fix.

Common repair costs for Bosch washing machine faults our engineers see regularly include:

• Drain pump replacement (E18, E23 codes): typically 80-150 pounds including parts and labour
• Door latch assembly (F34 codes): typically 70-120 pounds
• Pressure sensor replacement (E17, F21 codes): typically 90-160 pounds
• PCB control board (F28 codes): typically 150-350 pounds depending on the model and age
• Motor brushes or motor replacement (F43 codes): typically 100-250 pounds

If the repair cost sits above roughly 60-70% of the machine's current replacement value, most engineers will advise replacement rather than repair. For a Bosch machine that's 8-10 years old and already showing multiple fault codes, that's usually the right call. For Aylesbury landlords, getting a local engineer tends to be quicker than using a national appliance service plan, which can carry longer lead times for properties outside major city centres.

Documentation You Should Keep

Clear records protect both landlords and tenants if a dispute escalates, and the time to start keeping them is at the beginning of the tenancy, not after a fault appears.

Landlords should keep:

• A copy of the tenancy agreement or inventory listing which appliances are included and their condition at the start of the tenancy
• Records of any safety checks or PAT testing carried out before the tenancy began
• All correspondence with the tenant about the fault - including the date reported and the date responded
• Engineer invoices and job sheets, noting the fault code diagnosed and the work carried out
• Receipts for replacement appliances

Tenants should keep:

• Photographs of the error code on the display, with the date visible if possible
• Copies of all messages sent to the landlord, with timestamps
• Written responses received from the landlord or their agent
• A log of dates - when the fault first appeared, when it was reported, when an engineer visited

If a dispute ends up before a tenancy deposit scheme adjudicator or, in serious cases, a county court, a timestamped photograph of the fault code is considerably more useful than a disputed memory of "sometime in September". The Voltrade GoFIX diagnostic tool also generates a timestamped summary when you run a fault check, which some of our Aylesbury customers have used as supporting documentation in disputes.

Landlord and Tenant Questions

Is a landlord legally required to repair a washing machine in a rented property?

If the washing machine was included in the tenancy agreement, then yes - the landlord is generally required to keep it in working order under the Homes (Fitness for Human Habitation) Act 2018. If the machine was not included in the agreement, the legal position is less clear. Always make sure your tenancy agreement lists appliances explicitly, and note their condition in the inventory at the start of the tenancy. This protects both parties.

Can a landlord charge a tenant for a Bosch washing machine repair?

A landlord can charge a tenant for a repair if they can demonstrate the fault was caused by misuse or negligence rather than normal wear and tear. Common examples include a blocked pump filter that was never cleaned, or motor damage caused by consistent overloading. If the fault is mechanical or component-related - a failed pressure sensor, a worn pump, a faulty PCB - that would typically be the landlord's cost. The engineer's written diagnosis is usually the key piece of evidence in these situations.

Which Bosch error codes are serious enough to stop using the machine immediately?

Any code indicating water in the base of the machine - commonly shown as E13 on Bosch machines - means you should stop using it straight away and report it immediately. Similarly, F28 (motor control unit fault) and codes indicating a complete drain failure where water can't leave the drum should be treated as stop-and-report faults. Running the machine through further cycles when these are active risks water damage to the property, which could become a much larger issue than the original appliance fault.

How long does a typical Bosch washing machine repair take in Aylesbury?

For common faults like drain pumps, door latches, or pressure sensors, a local engineer in Aylesbury can typically diagnose on the first visit and return with parts within two to five working days. Less common parts - particularly older PCB control boards for discontinued Bosch models - can take longer to source, sometimes up to two weeks. If the repair is going to take more than a week, a responsible landlord should discuss interim arrangements with their tenant, particularly in family properties.

Does a tenant need to be present when the washing machine engineer visits?

In most cases, yes - an adult over 18 needs to be present to allow access and to confirm the fault with the engineer. Some landlords in Aylesbury arrange access directly with the tenant's agreement, but this should be confirmed in writing beforehand. The tenant should also be given at least 24 hours' notice of any engineer visit, except in a genuine emergency. After the repair, ask the engineer for a written job sheet confirming what was found and what was done - keep that document alongside your other tenancy records.
