Product review (4 stars): Is your Frigidaire FPH2491KF not cleaning - not draining. Replace the main circut board.
About a year ago my Frigidaire FPH2491KF dishwasher stopped draining plus the main wash motor (EAP2379482) seamed to only work intermittently. After doing some research I narrowed it down to a faulty board assembly. It takes about 30 minutes to switch out the part. I'm really disappointed with Frigidaire, particularly having major component fail within 18 months of ownership. I believe we paid over $700 for this model, I just expected it to last much longer. Only tools you'll need: #15 Torx & #2 Phillips screwdriver. There's now a youtube video showing the R&R procedure, just Google the model number. Should show up in either "web" or "video", first page. Don't forget to unplug the power cord before hand. Good luck

BTW: Nice to see the price drop to $102 (as of this writing) from $159....
