Hi, I have a Bush DWFS126S dishwasher that is showing E5 error code. There was a leak from the drain pump which appears to have been a faulty seal.. I have replaced this but the machine still shows E5 and therefore it will not run to test.. I've tried reseting this by tilting the macine and also holding the start button in.. to no effect. How can I reset? Suggestions will be much appreciated . Many thanks.
