When water is still inside after the programme
Describe the water level and display. Say whether the machine finished or stopped during the wash. Mention recent sink, waste-pipe or kitchen work: the appliance and its installation both need consideration. Water left inside does not prove that the pump has failed. Do not remove lower panels or tilt an integrated machine.
When the cycle ends but the wash result changes
Tell us what changed: dirty dishes, cold items, a film on glassware or poorer drying. Note whether every rack is affected and whether the change was sudden. Include any normal setting you changed or handbook advice you followed. A completed wash with poor results needs a different assessment from a cycle that stops early.
Bosch dishwasher E09: a heating fault
For Bosch dishwashers, E09 (also displayed as E:09) indicates a heating-element fault. Bosch recommends a professional repair because of the safety risks. Stop using the dishwasher and arrange an assessment; do not remove panels, test electrical parts or keep restarting it. Copy the complete display message and the E-Nr model reference from an accessible label or your paperwork. The code does not establish the correct replacement part or repair price for your model. If you typed EO9 with the letter O, check that the display actually reads E09 with a zero.
Bosch dishwasher E15: a leakage warning
For Bosch dishwashers, E15 is associated with water leakage. Record the exact code, the complete E-Nr and any water visible from a safe position. Leave the dishwasher unused and arrange an assessment; do not tilt it, remove panels or repeatedly restart it to clear the warning. Do not touch plugs or electrical equipment in a wet area. The source of a leak needs checking for that model: E15 is not proof that one particular part needs replacing.
Bosch dishwasher E24: a drainage warning
For Bosch dishwashers, E24 describes a drainage problem associated with a blockage. This is not the same report as an E15 leakage warning, and it does not by itself prove the pump has failed. Tell us whether water remains in the wash compartment and whether any sink or waste-pipe work happened before the problem. Consult the instructions for the complete E-Nr before routine user maintenance; leave fitted panels and hoses in place. If the exact procedure is unclear, or the machine is leaking or tripping the electrics, stop using it and request assessment.

The cited Bosch US guide describes an internal heater fault in the heat pump. This is not a confirmed replacement-part diagnosis.
Bosch dishwasher E21: heat-pump blockage
The cited Bosch US guide describes a blocked heat pump.

Bosch lists flow-meter failure or a filling/water-flow problem.
Bosch dishwasher E16 / E17: filling warning
Bosch identifies a problem with water entering the dishwasher.
Bosch dishwasher E18: low water-flow warning
Bosch describes low water level or an inlet/pumping problem.
Bosch dishwasher E22: drainage and filter warning
Bosch lists filter, pump-cover and drain-path restrictions as possible causes.
Bosch dishwasher E23: drain-pump warning
Bosch lists a blocked, clogged or faulty drain pump.
Bosch dishwasher E25: drain-path warning
Bosch lists pump, cover, hose or waste-path restrictions.
Bosch dishwasher E19: heat-exchanger guidance
Bosch UK describes E19 as a heat-exchanger problem and recommends professional assessment. Do not remove panels or repeatedly restart it to identify a part. Send the complete E-Nr and a photo of the display; code explanations from other markets can differ.
Safe checks and deciding your next step
For checks that do not involve dismantling the appliance, read the dishwasher safety guidance. If you are weighing up a repair and a replacement, see what affects that decision. Your exact model handbook takes precedence over general guidance.

If you are considering a replacement
A replacement dishwasher must work with the opening, furniture front, plinth and existing services. The nominal width alone does not establish compatibility, so send both model numbers before a fitting is agreed.

Bosch dishwasher repair questions
Does water in the base always mean the same fault?
No. The location and stage matter: water in the wash compartment, a leak onto the floor and a message during filling are not interchangeable observations. Tell us exactly what you can see safely and when it appeared.
Can the furniture door affect the visit?
Yes. The office should know that the dishwasher has a fitted kitchen front and whether the door opens freely. Leave the furniture door and plinth attached unless the engineer specifically arranges otherwise.
Can I book a Bosch dishwasher repair for an error code?
Yes. Copy the code exactly, including any additional digits, and include the E-Nr. Explain whether the dishwasher is not draining, not heating, leaking or stopping before the cycle finishes. Codes alone do not confirm a failed part; avoid repeated restarts if water is leaking or the power trips.
What affects the cost of a Bosch dishwasher repair?
For a Central London service address, the standard freestanding call-out is £90 plus parts. Integrated appliances of any brand start from £120 plus parts in Central London. Outside Central London, fixed call-out charges start from £75, depending on your appliance's make and model and whether it is freestanding, integrated or another appliance type. Our office confirms the service address and applicable amount by phone before arranging your visit. The agreed charge covers the first visit, repair labour and any return visit needed to fit parts for the same agreed repair. There is no extra labour or repeat call-out charge for that repair. Parts are priced separately and approved before fitting. Include the full E-Nr and any integrated furniture door or access restriction when you enquire.
Do wet plastics mean my Bosch dishwasher has a heating fault?
Not necessarily. Bosch notes that plastic retains less heat than other items and can remain wetter after a programme. Tell us whether the problem mainly affects plastics or the whole load, and whether washing results have also changed. Check loading space, rinse aid and any drying option using the exact model's handbook; features and programmes differ. Poor drying alone does not identify a failed heater. If the dishwasher no longer heats the wash water, stops with a warning or gives consistently poor results, include those details and the E-Nr when requesting assessment.
