Hi, I have recently moved to my flat and got a new Bosch washing machine which was working great. Today I was checking the flat's stopcock and just closed it and opened it to make sure it is working. Then I wanted to use my washing machine and gives error E29 which in the manual says" clean the filter or water pressure too low". As this happened right after me closing and opening the stopcock, it has got to be relevant? The sink tap working fine and water pressure from the tap is fine. I opened the blue hose (which is think is cold water hose) behind the washing machine and there was nothing stuck on the surface area with micro size holes that is on the washing machine. I disconnected the hose from the water supply side as well and run water through and doesn't seem to be blocked. Is it possible that there is a block inside the metal pluming beneath my sink?
