If a dishwasher doesn’t drain properly and / or shows an
E:25
error code, the problem could be the drain pump cover wasn’t
replaced properly (i.e. not completely seated and locked into
position). Loose drain pump covers allow more water flow to the
drain pump, increasing the pump load, drawing more current and
causing an
E:25
error code.
