Re: whirlpool generation dishwasher light blinks 3 times
Yup, no heat in the time allowed. Heater is a tube-type situated under the tub, so you have to pull it out and remove the bottom cover for access. Heater should read approx 25 ohms if it’s working. Connector at heater occasionally burns out.
If the heater has failed, we will need the actual model number of the appliance in order to identify the replacement part.
Power off before going in.
