my dishwasher waste became detached and I got a 30 error code,
I managed to clear this then I got 10 error code and then a 20
whatever I seem to do I keep getting these 3 different error codes
it is a John Lewis dishwasher that was working perfectly up until now
thank you

Have you contacted John Lewis or UK White Goods to ask about the fault codes?
