Re: Fisher & Paykel Dishwasher DW920 Fault Code 29
Hi-have had numerous probs with f and p dishwasher and the engineer who came out described a problem similar to yours. Apparently the buttons on the front of each drawer(when pressed for the right length of time in the right order!) perform many useful tricks.The one he used (apparently fixed a fault similar to your own) basically was a master reset. You hold down the lock button until it beeps and then you repeat this till it beeps again. et voila!
Maybe.
hope this helps.The software gets confused if a number of error codes build up-cured my problem of the touch panels stopping working.
