Kenmore dishwasher wont fill or run
Does the control panel include the controller circuit board (may be inside a plastic box behind the control panel)? If not, this is the first place to look. The control circuit box cover is most likely held on with latching tabs and can probably be removed using only a flat blade screwdriver to gently disengage the hooks on the tabs.
Once you have the cover off, visually inspect the electrolytic capacitors on the circuit board. To understand what you are looking for, check the pictures in this description of a TV repair (I'd borrow the images if I had obtained permission). A capacitor with a bulging top has most likely gone bad, and there may be more than one that has gone out. If this is the case, there are two numbers you need to get the right replacement(s): capacitance (e. g., 470 uF for a 470 microFarad unit - the "u" in uF is actually the Greek letter mu, but only English characters are permitted here) and maximum voltage (e. g., 25 V). Minimum/maximum temperature range is also part of the specification, but I generally get parts with -40 C - 105 C rating or better. The minimum temperature is not as critical as the maximum temperature. When I pick a replacement, I look for two other numbers: Endurance and ripple current rating. Get the highest values you can find for these. You may have to give up a little on the ripple current to get the endurance. I usually have the best results with Panasonic FR series capacitors.
Caution: unless you are familiar with anti-static handling procedures, do not touch or remove the circuit board - let an experienced electronic technician handle that; otherwise you can do more damage to it with electrostatic discharges from your fingers. Also, make sure the breaker for the dishwasher is turned off first so you don't zap yourself. Replacing the capacitors requires skill with removing and replacing soldered components.
