Our dishwasher is a Whirlpool, it was working fine, did a load of dishes and then tried to do another in the morning and it starts to fill for about 30 seconds or so then shuts off. The front panel lights click and blink every 5 seconds until we cancel the cycle. We tried to replace the motherboard and the fill pump to no avail. Any advice would be greatly appreciated!!! Thank you so much in advance!!
