Dead error code pf then died

trusty old dishwasher has flashed PF and no gone black
bought it used for $40.00 8 years ago. if i can fix this girl, will try:)

PF generally just stands for power failure which means your power or breaker went out at one point in time then it came back on typically…check at the junction box where the power comes in and see if you have 120v coming to the unit first…if you do have 120v present and the connection is good try a continuity check on the fuses in the system…also check the door switches continuity…i just checked sears site and your fuses may not be available possibly or their site is having issues…

how do i check the continutity of the fuses, or the continuity of the latch, will do it if you tell me how

Go to youtube and watch videos on how to do continuity tests…Good luck
