Bosch Dishwasher fault codes

E01 - Power Module/Low Voltage:
Bosch Dishwasher error E01 indicates a faulty power module or the voltage in the power point too low.

E02 - Power module faulty:
Bosch Dishwasher error E02 indicates a faulty relay on the power module.

E03 - Power module faulty:
Bosch Dishwasher error E03 indicates the working relay/Safety relay for auxiliary heater is defective.

E05 - Power module faulty:
Bosch Dishwasher error E05 indicates that the triac for water switch motor is defective.

E06 - Door hall sensor fault:
Bosch Dishwasher error E06 indicates that the wire to the Hall sensor interrupted or power module defective or hall sensor defective.

E07 - Drying fault:
Bosch Dishwasher error E07 indicates water in fan housing Heating-circuit Zeolite is intermittent.
Fan defective, optional electronic defect, wire is intermittent.

E08 - Heating Fault:
Bosch Dishwasher error E08 indicates that the heat pump detects too low water level in pump sump.

E09 - Heating Fault:
Bosch Dishwasher error E09 indicates that the heating circuit is interrupted (resistance, supply wires, contacts of the safety relay on power module).

E10 - Heating Fault:
Bosch Dishwasher error E10 indicates that the heating element thermal output too low, deposits on heating element.
Check water hardness; if necessary decalcify and clean. Change heat pump.

E11 - Heating Fault:
Bosch Dishwasher error E11 indicates that the NTC resistance values outside permitted range.
Wire or plug interrupted.

E13 - Heating Fault:
Bosch Dishwasher error E13 indicates that the water temperature is too high (>75 °C)
Protective measure – no appliance fault! Check temperature of water supply.

E14 - Filling Fault:
Bosch Dishwasher error E14 indicates no impulses from flow sensor, although water is detected by heat pump.
Check wires, test flow sensor (reed switch).

E15 - Filling Fault:
Bosch Dishwasher error E15 indicates that the base carrier safety switch active indicating a water leak. Appliance cannot be switched off.

E16 - Filling Fault:
Bosch Dishwasher error E16 indicates water supply (impulses from flow sensor) without activation of the filling valve.

E17 - Filling Fault:
Bosch Dishwasher error E17 indicates water supply rate too high according to flow sensor.

E18 - Filling Fault:
Bosch Dishwasher error E18 indicates water supply rate too low according to flow sensor or no water supply.

E20 - Circulation Pump Fault:
Bosch Dishwasher error E20 indicates resistance values of heat pump wrong.
Check wires / plugs
Measure resistance values of motor winding.

E21 - Circulation Pump Fault:
Bosch Dishwasher error E21 indicates a blocked heat pump.
Check heat pump for foreign objects, if motor seized replace the heat pump.

E23 - Drain Pump Fault:
Bosch Dishwasher error E23 indicates resistance values of drain pump wrong.
Check wires / plugs.
Measure resistance on the drain pump.

E24 - Drain Pump Fault:
Bosch dishwasher E24 error indicates that the machine is not able to drain the water.

E25 - Drain Pump Fault:
Bosch dishwasher E25 error indicates that the drain pump is jammed.
Drain pump cover missing from pump sump.

E26 - Water Switch Fault:
Bosch Dishwasher error E26 indicates no impulses from water switch despite actuation.

E28 - Aqua Sensor Fault:
Appliance without AquaSensor.
Calibration of AquaSensor not successful.
