This in-depth guide will explain the Whirlpool dishwasher 4 flashes error code, what it is, what will cause it, and how to diagnose and repair it.
Understanding the 4 Flashes Error Code
4 flashes error code on the Whirlpool dishwasher typically indicates a water temperature problem. The code serves to notify users of an apparent malfunction that can disrupt the operation of the dishwasher to wash dishes. Understanding the specification of this error code will help with effective troubleshooting and fixing.
Possible Causes of the 4 Flashes Error Code
Several reasons lead to the 4 flashes error code on Whirlpool dishwashers. The full list of reasons and fixes is presented below.
Failed Heating Element
Description: It warms water to the optimal temperature. A faulty heating element makes water too cold, and thus the 4 flashes error code appears.
Solution: Test the heating element for continuity with a multimeter. Replace the heating element with a new one if it is faulty.
Faulty Temperature Sensor
Description: The temperature sensor senses the water temperature and reports it to the control board. If the sensor is faulty, it may provide incorrect readings, and the 4 flashes error code will be activated.
Solution: Test the temperature sensor for continuity using a multimeter. Replace it with a new one if it is damaged.
Faulty Control Board
Description: The control board regulates the operation of the dishwasher’s operations, including water temperature. A faulty control board cannot regulate the temperature effectively, thus resulting in the error code.
Solution: Inspect the control board for visible damage or burnt components. If it is faulty, replace it with a new control board.
Low Water Supply
Description: Low water supply may be preventing the dishwasher from being filled with enough water to deliver the desired temperature, which will subsequently result in the 4 flashes error code.
Solution: Check the water inlet valve and hose for obstructions or kinks. Check that the water supply is adequate and the inlet valve is functioning properly.
Blocked Filter
Description: A blocked filter may restrict water flow, preventing the dishwasher from heating water properly and triggering the error code.
Solution: Clean the filter thoroughly to remove any debris or sediment. Make sure the filter is properly seated after cleaning.
Malfunctioning Thermostat
Description: The thermostat regulates the water temperature. When the thermostat is malfunctioning, the water becomes too cold, thus causing the 4 flashes error code.
Solution: Test the continuity of the thermostat using a multimeter. Replace the thermostat with a new one if it is faulty.
