Model Number: FGHD2433KF1
Brand: Frigidaire
Age: 6-10 years
My Frigidaire dishwasher seems to show the PF power failure after every wash now. We run it at night, so it’s unclear exactly when it fails and there are no other kitchen appliances that show a power failure so it’s localized to the dishwasher only.
It does seem to clean the dishes, and has a good amount of heat in the morning and no water in the tub, which to me indicates it’s failure during the heating cycle.
I don’t know how many heating/cleaning/drying cycles there are that activate the bottom heating elements, and since we’ve never watched it while it cleans/dries and triggers the PF display - I don’t know if it’s the control board, a shorted heating element or something completely different.
Everything I’ve read on DIY boards is this is likely the control board since there are no other error codes being displayed, and I haven’t seen anything about failing/shorting heating elements.
Any other suggestions on what to diagnose before ordering the control board replacement?
One other question - if I do replace this control board, what is the likelihood of this model needing more replacement parts or failing, since it is probably 10 years old (don’t know exactly when the previous owner installed it)?
