Try to contact the Grundfos service in your area, otherwise I don`t see much chance of getting the board, and probably no one will bother with the repair. Unless you have a friend who is an electronics enthusiast.
I have written to several authorized Grundfos services in my area. They won't sell tiles. I can see hard with repair. Direct Grundfos service "recommends" purchasing a new pump.
This is what a damaged tile looks like. Probably a transistor from the converter marked 1011B. I don`t know what was in the front because there is a hole. RMW marking at the top.
Hello, I will also join the topic because I have the same problem with pumps: ALPHA 2 25-40 180 ALPHA 2 25-60 180 Has your friend solved the problem and is there a chance to repair the pumps? The pumps do not respond when voltage is applied.
How to get to the pump electronics? How to disassemble it without damaging it? The red body fits tightly with the black element and I don`t know how to disassemble it.
I have marked in red the places where the hooks holding this "cover" are located. Only this pump is a slightly different model, but probably put together in the same way.
The discussion revolves around a Grundfos Alpha2 25-40 pump that ceased functioning after a storm, attributed to a damaged circuit board. Users suggest contacting local Grundfos services, but many report difficulties in obtaining replacement parts or repair services, with some being advised to purchase a new pump instead. A user shared a photo of the damaged circuit board, identifying a likely faulty transistor. Others have experienced similar issues with the Alpha2 series, with one user successfully repairing their pump by replacing a dead diode and fuse. Additional inquiries about disassembling the pump for repairs and potential leaks in seals were also raised. Summary generated by the language model.
