Midea Dishwasher Error Codes
Remember to always unplug the dishwasher and exercise caution when attempting any repairs.
E1: Water inlet valve error
When the flow meter can’t detect the water after 4 minutes, the E1 error will appear.
Causes:
- The water tap is closed.
- Too low a water pressure range is 1 MPa.
- The inlet valve hose is blocked, kinked, or frozen.
- Faulty inlet valve or aqua-stop
- Faulty water-liter counter
- Faulty main PCB
Solutions:
- Make sure the pressure in the water is good.
- Clean the inlet hose and the inlet valve filter.
- Check the wire harness connector.
- Check the solenoid valve resistance.
| Electric part name | Ohmic value |
|---|---|
| Water inlet valve | 3–4.3 KΩ |
- Check the flowmeter (reed switch):
- When the magnet comes close to the reed switch, the contact stays closed.
- When the magnet moves away, the contact of the reed switch opens.
- If the error still occurs, replace the main PCB.
E2: Drain pump motor error
Causes:
- Clogged filter, drain hose, siphon…
- Faulty drain pump
- Faulty main PCB
Solutions:
- Check the drain pump hose or filter.
- Check the drain pump motor resistance.
| Electric part name | Ohmic value |
|---|---|
| Drain pump | 180 Ω |
- If the error still occurs, replace the main PCB.
E3: heater assembly error
When the temperature can’t reach the defined value after 9 minutes, the E3 error will appear.
Causes:
- Faulty wire harness.
- Faulty safety thermostat 1
- Faulty safety thermostat 2
- faulty heating elements.
- faulty pressure switch.
- Faulty main PCB
Solutions:
- Check the wire harness connector.
- Check the safety thermostats 1 and 2 for resistance:
| Electric part name | Temperature | Ohmic value |
|---|---|---|
| Safety thermostat 1 | 209 °F | 0.1 Ω |
| Safety thermostat 2 | 445 °F | 0.1 Ω |
- Check the heating element resistance.
| Electric part name | Ohmic value |
|---|---|
| Heater assembly | 29 Ω |
- Check the water level switch resistance:
| Electric part name | Ohmic value |
|---|---|
| pressure switch with water | 0.1 Ω |
| pressure switch with no water | open-loop or ∞ Ω |
- Check the washing pump motor for blockages.
- If the error still occurs, replace the main PCB.
E4: Water leakage error
Causes:
- Faulty wire harness.
- Damaged hoses.
- Faulty anti-flood overflow float switch
- Faulty pressure switch.
Solutions:
- Check the wire harness connector.
- Find where the leakage is!
- Replace the hose that is causing the problem.
- Replace the anti-flood.
- Replace the water level switch.
E6: NTC sensor open-circuit error
Causes:
- Faulty wire harness.
- Faulty NTC.
- Faulty main PCB
Solutions:
- Check the wiring between the NTC sensor and the board.
- Check the NTC sensor resistance.
| Electric part name | Temperature | Ohmic value |
|---|---|---|
| NTC sensor | 77 °F | 10000 Ω |
- If the resistance value is wrong, replace the sensor.
- Check the main PCB and replace it if necessary.
E7: NTC sensor short-circuit error
Causes:
- Faulty wire harness.
- Faulty NTC.
- Faulty main PCB
Solutions:
- Check the wiring between the NTC sensor and the board.
- Check the NTC sensor resistance.
| Electric part name | Temperature | Ohmic value |
|---|---|---|
| NTC sensor | 122 °F | 4201 Ω |
- If the resistance value is wrong, replace the sensor.
- Check the main PCB and replace it if necessary.
E8: Diverter valve error
Causes:
- Faulty wire harness: open circuit, leads off place, or loose.
- Faulty diverter microswitch
- Defective diverter micromotor.
- Faulty main PCB
Solutions:
- Check the wiring between the diverter valve and the board.
- Replace the diverter valve.
E9: Shorted key error
When some buttons have been pressed for over 30 seconds, the dishwasher will be warning for E9.
Causes:
- Misuse by the customer.
- The presence of moisture on the buttons.
- Faulty control panel.
Solutions:
- Switch off the appliance and switch it on again, and check if the error disappears.
- Clean the control board with the appropriate cleaner (PCB cleaner).
- Replace the control board.
Ed: Communication failure
When the display board can’t receive or the main board can’t send a signal for over 20 seconds, the Ed error will appear.
Causes:
- Faulty wire harness (open circuit, leads off place, or loose).
- Faulty control board.
- Faulty main PCB
Solutions:
- Check the wiring between the main PCB and the control board.
- Replace the control board.
- Replace the main PCB.
EC: BLDC motor error
Causes:
- Faulty wire harness.
- Faulty BLDC motor wash pump
- Faulty inverter board.
- Faulty main PCB
Solutions:
- Check the wiring between the main PCB and the BLDC motor.
- The resistance measurement between the BLDC windings should be the same:
| Electric part name | Ohmic value |
|---|---|
| BLDC motor | U and V = V and W = W and U = 59 Ω |
- Check the inverter board. Replace it if necessary.
- Check the main PCB. Replace it if necessary.
