Heats the water and pumps it round the dishwasher during the wash.
Tick the symptoms your appliance is showing. We’ll tell you how confident we are this part is the fix.
Error codes are model dependent, so the same brand may have more than one listed.
| Code | Brand | What it means | Confidence |
|---|---|---|---|
| E11 | Bosch | Means a heating fault where the water is not reaching the required temperature, often leading to cold or wet dishes and premature cycle termination. It is usually caused by a faulty NTC temperature sensor (thermistor), a failed heating element or heat pump, or wiring problems. | High |
| E12 | Bosch | Means heavy limescale buildup on the heating element (heat pump), causing slow heating or heating failure. It is usually caused by limescale buildup, common in hard water areas. | High |
| E2 | Bosch | Means the heater cannot heat the water properly. It is usually caused by a fatal fault with the main control board relay, or a malfunction in the heating system or NTC sensor. | High |
| E4 | Bosch | Means a heating system failure that causes cold washes, poor drying, and interrupted cycles. It is usually caused by a faulty heating element, thermistor (temperature sensor), or a malfunctioning heating pump. | High |
| E9 | Bosch | Means a heating circuit failure where the water cannot heat up, leading to cold or wet dishes. It is usually caused by a burnt-out heating element or a faulty heat pump module, with limescale buildup from hard water and electrical surges common contributors. | High |
| E11 | Neff | Means the water is not reaching the required temperature or the sensor is failing to detect it. It is usually caused by a faulty NTC thermistor, a heating pump failure, or wiring problems between the pump and control module. | High |
| E12 | Neff | Means the heater cannot warm the water properly because of significant limescale buildup on the heat pump, common in hard water areas. It is usually caused by limescale buildup on the pump, with a blocked filter also contributing. | High |
| E13 | Neff | Means the water temperature inside has exceeded 75C or the heating system is malfunctioning. It is usually caused by connecting the appliance to a hot water supply instead of cold, or a faulty NTC temperature sensor. | High |
| E2 | Neff | Means there is a heating fault leaving cold water and incomplete drying. It is usually caused by a failed heating element, a faulty relay on the control module, or a heating module malfunction. | High |
| E3 | Neff | Means the machine is not heating the water or is taking too long to reach the set temperature. It is usually caused by a failed heating element, a faulty heating pump, or a malfunctioning temperature thermistor. | High |
| E5 | Neff | Means there is a heating fault, a temperature sensor issue, or a water inflow problem, often on Zeolith models from circulation pump struggles. It is usually caused by a circulation pump struggling, a failure to heat water to temperature, or a blocked filter. | High |
| E8 | Neff | Means there is a heating circuit fault because the system cannot detect enough water flow through the heating system, leading to the machine stalling. It is usually caused by the water level being too low for the heater, a blocked filter, a pump failure, or low water pressure. | High |
| E9 | Neff | Means there is a serious heating system failure leaving cold, wet, and often greasy dishes at the end of the cycle. It is usually caused by a burnt out heating element integrated into the circulation pump. | High |
| E10 | Siemens | Means the water is not heating during the cycle, which can leave dishes poorly dried. It is usually caused by a faulty heat pump, a faulty heating element, or a need for descaling. | High |
| E11 | Siemens | Means the dishwasher does not heat water, leaving dishes cold, dirty, or wet, and often ends the cycle early. It is usually caused by a faulty NTC temperature sensor (thermistor) or a heating element failure. | High |
| E2 | Siemens | Means the machine cannot heat water. It is usually caused by a faulty heating element, a heater relay, or a temperature sensor. | High |
| E31 | Siemens | Means the dishwasher cannot heat water or detect sufficient water levels to continue the cycle. It is usually caused by a fault in the heat pump or the water supply. | High |
| E9 | Siemens | Means there is a heating problem that often results in cold washes or a cycle that shuts down early. It is usually caused by a failed heating element within the heater-pump assembly. | High |
| E3 | Whirlpool | Means the water is not heating properly or the heating element is malfunctioning. It is usually caused by a blocked filter, excessive sudsing, or a failure to heat. | High |
| H1 | Whirlpool | Means a heating circuit fault where the unit is having trouble heating water, or that a delay start is active. It is usually caused by a faulty control board or a failure to heat. | High |

General fitting guidance. The exact steps can vary slightly with the make and model of your dishwasher.
Safety: Switch off and unplug at the mains before you start.
This is a genuine dishwasher heat pump replacement.
Does two big jobs in one—it pumps water around your dishwasher and heats it up for a proper clean. The motor keeps the water moving through the spray arms, and the built-in heater brings it to just the right temperature for tackling tough food bits.
If your dishwasher’s not cleaning as well as it used to, or the water doesn’t feel hot enough, the heat pump might be worn out. Hard water, heat, and everyday use can take a toll. Swap it out with this part.
This heat pump for your dishwasher is from Bosch. It also fits the list of brands mentioned above.
Before ordering, please verify with our compatibility checker that this part is suitable for your model.
Can't fault this transaction, part arrived quickly, was exceedingly simple to fix and worked first time. This was after a so called appliance engineer said the part we needed was no longer available and tried to sell us a replacement dishwasher costing 5 times what this part cost.
I always buy genuine manufacturer parts as they often come with all the necessary extra bits. This had a good hose clip included, which you will need, and a plastic bit, which I've fitted but I'm not sure why. Looks identical to the removed plastic bit which didn't need replacing but I'm guessing there's a reason. Machine fully functional again.
Part was easy to find, swift delivery. Very happy
Great product, very easy to fit came with instructions and easy to read and follow. Great service, delivered very quickly on time.
I would recommend Ransom spares. The price was good, delivery was prompt. Excellent service
