These fault codes are written for dishwasher repairers and not for the general public by Hotpoint and they assume a certain level of competence on the part of the user in diagnostic routines. We may have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits.

Please check that any Hotpoint dishwasher spares recommended are suitable for use on your particular model and serial number. If you are unsure about the suitability of any spare part please ask to ensure that you get the correct spares for your particular dishwasher model.
