DISHWASHER COMMON PROBLEMS

Your dishwasher doesn’t drain the water
Cause: Dishwasher drain hose kinked or clogged
Easy dishwasher repair solution: Look for bends and straighten them. If the dishwasher hose won’t stay straight, buy a helical spring which is a bit larger than the outer diameter of the dishwasher hose and place it around the hose to keep it straight. If the hose is straight, disconnect and blow through it to see that it is clear.
Cause: Dishwasher timer sticks in “Wash” phase
Easy dishwasher repair solution: If the dishwasher timer doesn’t advance from the “Wash” to the “Drain” phase, the timer is defective and should be replaced.

Your dishwasher detergent-cup lid fails to spring open
Cause: Dish or utensil is blocking the dishwasher lid
Easy dishwasher repair solution: Make sure dishes and utensils are positioned so they can’t possibly jam against the dishwasher detergent-cup lid.
Cause: Detergent put into a wet cup or left in the cup too long
Easy dishwasher repair solution: The cup should be dry when the dishwasher detergent is put into it, because the detergent will harden in a wet cup and may cause the lid to jam. If the dishwasher detergent remains in the cup for too long a period, it may cake.
Cause: Hard-water deposits (calcium) are hampering lid operation
Easy dishwasher repair solution: Clean the dishwasher cup and lid with vinegar.
Cause:Dishwasher detergent-cup lid solenoid valve is defective
Easy dishwasher repair solution: Consult the dishwasher wiring diagram and locate the solenoid. Place a continuity tester across the dishwasher solenoid

Your dishwasher doesn’t dry the dishes
Cause: Improper placement
Easy dishwasher repair solution: Air space should be left around the dishes to permit free passage of heat.
Cause: Calcium deposits have built up on dishwasher heating element
Easy dishwasher repair solution: Examine the element and clean off deposits with vinegar.
Cause: A wire has come loose from the dishwasher heating element
Easy dishwasher repair solution: Be sure wires are tightly attached.
Cause: Heating element has burned out
Easy dishwasher repair solution: Test the dishwasher element for continuity by placing a tester across its terminals. If there is continuity, the dishwasher element has failed. Replace it.

Dishwasher mechanical components are usually mounted directly to the tub it’s important that you know how to troubleshoot the dishwasher motor, look at the bell housing on the dishwasher motor and determine if it has a manual-reset protector. No hum or noise at all?

Check for voltage at the dishwasher motor terminals with a volt-ohm meter (VOM). A relatively loud hum (less than four seconds) followed by the overload protector kicking out indicates that both running and starting windings are being energized; check for foreign object or impeller, or stuck dishwasher motor bearings. If it hums or buzzes for a longer period, chances are that the run Winding only is being energized, check the motor centrifugal switch. Problems in this area require removal and dis-assembly of the dishwasher motor. It’s best to let a dishwashers motor-repair shop replace the switch; it must be fabricated to fit the motor. The impeller itself is critical. Chips and breaks on the leading edge because erratic sprays patterns and greatly reduce washing efficiency. Damage to impellers is caused by foreign objects, primarily silverware, dropping into the sump.

If confronted with thin problem, inspect the silverware basket and be certain the machine is being loaded according to instructions.  The shaded-pole motor that powers the pump is a rugged device. If water doesn’t pump out, check to see the pump is turning freely; you can often tell by turning the motor shaft with long-nose pliers. If it’s binding, disassemble the pump and inspect for foreign objects. Motor bearings are usually accessible and will seldom require more  than cleaning and oiling if the motor shaft itself is binding.  A strainer, usually in the bottom of the tub, protects the dishwasher pump a compromise, however; its openings must be large enough to allow soft food deposits to pass and be flushed away, but small enough lo stop bits of bone, glass, olive pits, etc. The problem lies in small pieces of hard material. Check the strainer carefully whenever a foreign object is found in the pump. It’s a tough feeling when you reassemble the pump only to hear the “chunk” of another object logging against the impeller. If the dishwasher pump turns freely, check the pump motor for continuity with your volt meter.
