Re: Error E4 on Necht Dushwasher
I have the same problem iwth mine. I have Googled this subject and with a combination of all the advice I have found, I did the following:
Tilted the dishwsher slightly backwards. The dishwasher now works again. Basically the float switch needed a bit of encouraging to reset.
I have also decided to use the dishwasher specific salt granules and not rely on the 3 in 1 for keep it going.
Thanks for the suggestions.
