Appliance Repair Questions? Ask a Technician for Answers ASAP
Would you kindly let me have the product PNC which is on the rating label - a 9 or 11 number product code.
Here is the answer to your question - all I20 faults ie 20 21 22 23 24 equate to draining problems, be they taking to long, are not happening, or you have a blockage restricting the dishwashers abiltiy to drain in its allocated time period. First thing I would do is pour a kettle of boiling water into the sump of the appliance leave it a couple of minutes and then do a pump out and see if all the hot water is drained.
