What to do if the Xiaomi Tabletop Dishwasher displays the error code “E4”?
The error code “E4” indicates that the temperature sensor of the Xiaomi Tabletop Dishwasher has an error or the current water temperature exceeds a specific range.
To resolve this issue, please refer to the following steps:
1. Lay the device down and open the bottom panel. Check if the thermistor wiring harness is loose;
2. If the thermistor wiring harness is loose, reconnect the harness and reinspect;
3. If the thermistor wiring harness is not loose, check if the voltage at the thermistor terminal is within the normal range. If the voltage is within range, use a multimeter to measure the thermistor resistance. If the resistance is outside the range, replace the thermistor. If the voltage at the thermistor terminal is outside the normal range, use a multimeter to check the continuity of the thermistor wiring harness. If continuity is poor, replace the wiring harness. If the thermistor wiring harness has normal continuity, check the voltage at the thermistor terminal on the power board. If the voltage is outside the normal range, replace the power board and retest.
