Have owned for 3 months installed for 1 week. Had 4 week wait for a replacement drain hose after finally getting samsung to replace defective factory hose. Now that we have run 2 cycles through it we are getting a 4E code...Water supply... I checked pressure seems much more than adequate, checked filter screen...clean. Now we think it is an internal sensor/ valve. What a piece of JUNK!!! I cant wait to pay for these service calls when the warranty is up. If I could I would take it back and buy back the old wonder we had...it may have cleaned poorly but at least it cleaned!!!!
