What to do if the Xiaomi Tabletop Dishwasher displays the error code “E2”?
The error code “E2” indicates that the circuit for heating of the Xiaomi Tabletop Dishwasher has an error. You can resolve this issue by checking external factors and internal device factors.
To check the external factors, please refer to the following steps:
1. Check if the dishware is arranged correctly. Incorrect placement can trigger a heating error. Please arrange them properly and reinspect;
2. Check if the filter and spray arms are clogged. Clogs can prevent water from effectively returning, resulting in insufficient heating. Please clean them and reinspect;
3. Check if the dishwasher is receiving hot water. Hot water can cause the water temperature inside the dishwasher to become too high. If this happens, allow cold water to enter and reinspect.
To check the internal device factors, please refer to the following steps:
1. Check if the wash pump wiring harness is loose. Reconnect the wiring harness and reinspect;
2. If the wiring harness is not loose, use a multimeter to measure the resistance of the wash pump heating element. It should be between 33-38 ohms. If the resistance is abnormal, replace the wash pump;
3. Use a multimeter to check if the heating element wiring harness is continuous. If there is no continuity, replace the corresponding wiring harness;
4. If the heating element resistance is normal but the fault persists during program operation, measure the voltage at the heating element terminals during the heating phase to ensure it is within the standard range (local voltage range);
5. If there is no signal output from the power board terminals, replace the power board.
