I purchased 2 top loading speed queen commercial washers for my launderette, both have been out of order for 8 weeks, engineer said it was water pump I bought a new one however, that hasn't worked either. I have now been told it is the hot water valve on both machines that are faulty so now I'm looking for two replacement hot water valves and can't find a source for parts. Can you help please?
