Gibson Dishwasher not draining
If your Gibson dishwasher is not draining and you’re seeing standing water in the tub, start with the most common cause: clogged sump filters in the sump assembly. A blocked coarse filter or fine filter can restrict water flow and lead to a dishwasher clogged drain situation. If the filters are clean, the next likely problem is the drain pump. A failed drain pump motor or damaged impeller can keep the dishwasher water not draining through the drain hose. After that, check the control board, since a bad board may not send power to the drain pump. Less common but still important causes include a broken drain impeller, a failed drain solenoid kit that won’t open the drain valve, or a drain valve clogged with debris or stuck shut. In some cases, what seems like a dishwasher drain pump not working is really a valve or impeller issue. RepairClinic.com makes it easier to track down the exact fix. Enter your Gibson dishwasher model number to find the right replacement drain pump, control board, drain impeller, drain solenoid kit, drain valve, filter, or drain hose for your specific machine.
01 - Clogged Sump Filters
The sump assembly, located at the bottom of the dishwasher tub, contains the pump motor or motors to both circulate and drain the water. There are usually two filters in this assembly to strain food particles: a course filter and a fine filter. If the filters are clogged, the unit will get low water flow and poor washability. To clean filters, remove them from the sump and wash them with soap, warm water, and brush. If the filters are damaged, they should be replaced.

02 - Gibson Dishwasher Drain Pump
The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.

03 - Gibson Dishwasher Control Board
A dishwasher's control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the drain pump, preventing it from drawing the water out of the tank and forcing it through the drain hose to the garbage disposal or sink drain pipe.

04 - Gibson Dishwasher Drain Impeller
The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.

05 - Gibson Dishwasher Drain Solenoid Kit
The drain solenoid opens the drain valve to allow the water to exit the dishwasher. If the drain solenoid fails the valve will not open causing the dishwasher not to drain.

06 - Gibson Dishwasher Drain Valve
Over time, the drain valve can get clogged with debris. To ensure that water can flow through the drain valve, clean out the valve. If the drain valve is clear of debris but it still won’t actuate, replace it. Drain valves are not repairable—if the drain valve is defective, you must replace it.
