4E

No water detected in the tub for 6 minutes after starting the dishwasher

Check/Repair

Fully open the water supply cut-off valve for the dishwasher. If the valve is already open, unplug the dishwasher and shut off the water supply, and then disconnect the fill line and examine the water inlet valve. If the inlet screen is clogged, replace the water valve-don't just clean the screen, because debris could enter the valve body, causing the valve to stay open, resulting in flooding. Check the wiring connections on the water inlet valve and secure any loose connections. If the water valve won't open when activated, replace it.

Possible parts
Water inlet valve

Check/Repair

Check the temperature of the hot water at your kitchen faucet. If the temperature is above 120 degrees, lower the setting on the water heater. If the water temperature is below 176 degrees, the thermistor (temperature sensor) is defective. Replace the thermistor. If the problem persists, replace the main power board assembly (PBA).

Thermistor, Main power board assembly (PBA)

The thermistor (temperature sensor) detects 176 degree water or above in the tub

Check/Repair

Unplug the dishwasher or shut off the house circuit breaker to disconnect electrical power. Carefully open the dishwasher door and check the temperature of the water in the tub. If the water is close to 176 degrees, the heater relay on the main power board assembly (PBA) is likely stuck in the Closed position; replace the main PBA. If the water is less than 176, the thermistor (temperature sensor) is likely defective. Replace the thermistor. If the problem persists, replace the main PBA.

Thermistor, Main power board assembly

Half-load component failure

The diverter assembly controls spray-arm water flow in the half-load mode. Unplug the dishwasher and reconnect any loose wires on the diverter motor and diverter positions switch. Replace the wire harness if damaged. If the wires are okay, replace the diverter assembly, which includes the diverter motor, position switch and diverter plate. On some models, you'll need to replace the entire sump and motor assembly because diverter compoenents aren't available as separate parts.

Possible parts
