I have an Omega dishwasher and lately it hasn’t been cleaning utensils well.
I checked all the pipes and drainage stuff but didn’t solve. Got a guy to inspect and he did exactly the same things which I had already done go online help. However he noticed that both upper and lower arms weren’t moving. He suggested we replace them both.
My concern is that what if the pump is not working properly and the not able to generate enough for the arms to move. I removed the arms and tried using garden hose and one of them did spin perfectly. This guy seemed to think the pump is OK. Everything else like draining and water jet through the arms is ok.
Don’t want to do hit and trial and replace the arms for 100 bucks and then find pump faulty.
