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.

Most common repairs needed to fix a Bosch dishwasher

Detergent Dispenser Replacement

The detergent dispenser releases detergent and rinse aid at the proper times during the dishwashing cycle. When the cap for the rinse aid dispenser is worn or damaged, it won’t close properly and rinse aid will leak out of the dispenser and onto the dishwasher door. A worn or damaged gasket on the rinse aid cap will also allow rinse aid to leak out of the dispenser. Check the detergent dispenser for damage. Replace the dishwasher detergent dispenser if you find a damaged rinse aid cap or rinse aid gasket. Have a service technician replace the detergent dispenser if you’re unable to replace that part yourself.

PCB Replacement

The PCB is the electronic control board that controls dishwasher operations such as filling, washing, rinsing, detergent/rinse aid dispensing, draining and drying. When your Bosch dishwasher has rinse aid leaking, the PCB may be sending electric current to the detergent dispenser to dispense rinse aid constantly, randomly or at the wrong time in the cycle. When you see rinse aid dispensing out of the detergent dispenser and onto the door of the dishwasher, schedule dishwasher repair service and we’ll send a Sears Home Services technician to your home to fix the problem.

Wire Connector Replacement

Wiring connectors in the detergent dispenser circuit could be at fault for Bosch dishwasher rinse aid leaking. A shorted or damaged wiring connector could allow current to flow to the detergent dispenser rinse aid actuator at the wrong time so rinse aid would leak onto the dishwasher door. A technician will need to check the wiring connectors in the detergent dispenser circuit to find and correct this type of problem. When you see rinse aid leaking from the detergent dispenser in your Bosch dishwasher, schedule dishwasher repair service to have a Sears Home Services technician visit your home and find the cause of the problem.
