My Frigidaire dishwasher was displaying code i30 and it is now displaying i40. It will not run and I have looked into it and there seems to be no issue. What should i do?
Carlos Carias,
Error code i20 on a Frigidaire dishwasher is a drain issue. Check drain pump and hose for clogs.
There is a PLUG in the side of the garbage disposal that is intact (when you install a new disposal). This KNOCKOUT PLUG needs to be REMOVED if you are going to be using a dishwasher in conjunction with the dishwasher so the drain water can enter and drain from the dishwasher.

My Frigidaire dishwasher is showing error code i20. Drain is attached to a food disposer. Can you tell me what do you mean by “knockout plug has been removed”?
Thank you
Teace Speer,
Press the heat dry and start/cancel pads for 5 seconds. The dishwasher should begin to go through a test cycle. If you do this, does anything happen.. Power comes back? Dishwasher begins test cycle?
When all the lights flash it may indicate a power failure.
Has the power gone out recently?
You flipped the breaker ON/OFF, have you tried looking at the dishwasher outlet to be sure the GFCI has not reset?
If nothing happens still, you may have a fuse on the board that is bad or the main control board is bad.

All the lights on my dishwasher were blinking and the code on the screen read “00” so I turned off the power at the breaker for 5 minutes. Since I flipped the breaker back on, the dishwasher won’t respond at all. The panel is completely dark and it won’t turn on at all.
Barbara West,
Frigidaire dishwasher manual says UO error code is vent assembly error.
Check the wiring and connections first.
If the wiring and connections are okay, then you should replace the vent assembly.
If that did not solve the problem, then you need to replace the main control board.

Trying to repair error code “UO” on Frigidaire dishwasher as can’t afford repairman. I am 78 yrs old and need simple directions for repair. Thank you.
