Great video. Thanks for sharing it. My heat pump has failed. The 3 pin connector from the wire has one area around a pin slightly black and the heat element has some black burned tracks on the solder joints close to the 3 pins. What cause the connector to fail? The rest of the heat element looks as good as new. The damage is on the track close to the pins only.
Yes the damage initially starts on the pins due to leaks. Then you can solder the track but effectively this is short lived as they will break again. When you apply heat to the heater track surface it delaminates. So best option would be to replace the heat pump
Hi, the two purple wires coming out of the circuit board, one goes to the heat pump, where does the other go? I've disconnected mine, changed heatpump, but only removed 3 cables. Don't remember moving the second purple cable from anywhere. Help would be appreciated
Only drain and wash pump have purple cable. There is 3 wires on each cable set. On the motherboard side Bosch state never to remove the individual plugs from the cable guide as they are not fool proofed. I think they did this purposely to prevent unauthorised people from working on the machine. Send me a photo on the location of the connector

Is it possible to change only the heater
Hello Abbas
Not really the heater is a part of the wash pump. Once the heat pump is opened the sealing is compromised and should not be used.
Hi Abbas
Always replace the entire heat pump, the heater cannot be replaced by itself, as it is a part of the wash pump assembly
