The Definitive Guide to Fisher & Paykel Dishwasher U6 Error
Fisher & Paykel dishwashers are very reliable and technologically advanced. Being any other household appliance, sometimes they also develop faults that lead them to malfunction. The most common fault users face is the U6 error code. This definitive guide will define the Fisher & Paykel dishwasher U6 error, its cause, possible causes, and how to diagnose and repair it.
Explaining the U6 Error Code
Fisher & Paykel dishwasher error code U6 is typically a water temperature issue. That is, it indicates that the dishwasher cannot warm up the water to the desired level within the given time. This causes the diswashing cycle to be interrupted, and the dishes are not sterilized. It is important to know the error code in order to troubleshoot and repair the fault.
Possible Reasons for the U6 Fault Code
The U6 fault code in a Fisher & Paykel dishwasher has a number of possible causes. Some of them are listed below along with the possible solutions.
Faulty Heating Element
Explanation: The heater element heats the water to the right temperature. In case the heater element is faulty, the water fails to heat to the right temperature and hence causes the U6 error code.
Solution: Check the heater element for continuity using a multimeter. If faulty, replace it with a new one.
Description: The temperature sensor measures the water temperature and feeds it to the control board. The faulty temperature sensor feeds the control board with erroneous readings, which lead to the U6 error code.
Solution:.Check the temperature sensor for continuity with a multimeter. Replace it with a new one if faulty.
Faulty Control Board
Description: The control board controls the operation of the dishwasher, e.g., temperature. A faulty control board cannot control the temperature, and an error code is retained.
Solution: Check the control board for burn or damaged components. Replace the control board with a new one if the control board is faulty.
Low Water Supply
Description: Low water level in the supply does not allow the dishwasher to fill to a point where it can heat to its set temperature, thus the U6 error code.
Solution: Ensure that water hose and inlet valve are not kinked or clogged. Verify if there is proper water supply and if inlet valve is in working condition.
Filter Clogging
Description: Clogging of the filter may block the water path through the filter, preventing the operation of the dishwasher to heat water efficiently and causing the error code.
Solution: Clean the filter thoroughly to clear any debris or deposits. Properly seat the filter after cleaning.
Faulty Thermostat
Description: The thermostat controls the water temperature. Since the thermostat is not functional, it will chill water, and thus, will produce the U6 error code.
Solution: Test the continuity of the thermostat with a multimeter. If the thermostat is faulty, replace the same with a new thermostat.
