Hi, I think there was a similar problem with the Melitta Bistro KVAs. Two electrolytic capacitors were usually the main culprit there. The inner workings of these two KVAs are probably very identical. Perhaps this will bring you closer to the solution. |
Thanks for your reply. I did some more troubleshooting and the 12-24 control valve is also defective.
After disassembling, I find the model designation rs-545sh-18150 on the motor, which seems to be a normal DC-DC. Miele want 430 euros for it, but in my opinion the motor is at fault and not the valve itself. On eBay, for example, you can find this

Does anyone know, if the motor can be replaced by the one mentioned above? However, it says 12-30 V, but the model is identical. There is a number under the model name itself that starts with QD. All motors start with QD, but the numbers are different. Does each individual motor have a specific specification or is it e.g. serial number?
Thanks for any answers,
