    Most common repairs needed to fix a Bosch dishwasher

    Electronic Control Board Replacement

    When your dishwasher is getting no heat, it could have a defective electronic control board. The control board sends current to the heating element when it’s working properly. A failed relay or corrupted logic on the circuit board could prevent the control board from sending electrical current to the heating element. Determining whether an electronic control board is defective is difficult. Have a Sears Home Services Repair Expert visit your home and fix the dishwasher when it is not heating.


    Water Valve Replacement

    If the dishwasher won’t heat, a clogged fill valve could be preventing the heating element from working. Low or no water entering the dishwasher will quickly cause a high-temperature safety thermostat on the bottom of the tub to trip and shut off power to the heating element. That safety thermostat won’t reset until the tub cools down and will then trip again if the tub isn’t filled with water. Have a Sears Home Services Technician fix your dishwasher when it won’t heat and isn’t filling properly.

    Detergent Dispenser Replacement

    When your dishwasher won’t heat, a broken detergent dispenser could be causing the failure. A bad water seal around the base of the detergent dispenser can allow water to enter the inner door panel and short out wiring or internal components in the dispenser. A shorted dispenser or wiring can prevent the electronic control board from sending electric current to the dishwasher heating element. When the dishwasher won’t heat, have a Sears Home Services Expert examine your appliance and replace the broken detergent dispenser.

    What to expect when you experience a Bosch dishwasher no heat issue

    How is the no heat problem fixed?

    Correcting most no heat problems usually involves replacing the electronic control board, water valve or detergent dispenser. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    Sears Home Services recommendations for a dishwasher that won't heat

    When the dishwasher has no heat it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

    What to look out for with a dishwasher no heat diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

    Thorough

    James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
