Error codes related to this part
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 |

More Details
This is a genuine dishwasher heat pump replacement.
The pump includes a wash motor and a heating element. The wash motor circulates water, and the heating element raises the water temperature during wash and rinse cycles.
Hard water, poor maintenance, and excessively hot water can damage the heat pump. When damaged, it causes reduced efficiency, wear and tear. Change it with this replacement part.
This heat pump for your dishwasher is from Bosch. It also fits Balay, Constructa, Gaggenau, Ikea, Neff, Pitsos, Profilo, Siemens, and Viva dishwashers.
Before ordering, please verify with our compatibility checker that this part is suitable for your model.
