E1
Midea E1 on dishwasher: water filling exceeds preset time
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
E1 on Midea dishwashers indicates a longer water inlet time because the required water volume was not reached within 4 minutes. Check that the water supply tap is fully open, the inlet hose is not kinked, and house water pressure is adequate before calling a technician.
Safety first
Stop and check this first
- Always disconnect the dishwasher from the electrical outlet and shut off the water tap before unscrewing the inlet hose or performing maintenance.
- If overflow or water in the base pan accompanies an error code, turn off the main water supply immediately before calling service; non-professional repairs create safety risks and affect warranty coverage.
Safe checks you can perform
- Check that the water supply faucet is fully open and flowing
- Inspect the water inlet hose and drain hose routing
- Clean the water inlet filter and internal sump filters
- Technician inspection of inlet valve, flowmeter and pressure switch
Leave these tasks to a qualified professional
- Do not attempt this professional task: Test inlet valve coil resistance (3.4-4.8 kilohms) and clean or replace valve
- Do not attempt this professional task: Check and repair the flowmeter or pressure switch circuit
- Do not attempt this professional task: Verify drain pump operation (235 ohms) to prevent pressure switch trip
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Test inlet valve coil resistance (3.4-4.8 kilohms) and clean or replace valve
What they doWith power disconnected and the tap closed, the technician unplugs CON3/EV1 and ACN to measure inlet valve resistance, clears any residue from the valve filter, and replaces the inlet valve or Aquastop safety hose if the coil is broken or locked.
They must show youthe multimeter kilohm reading across EV1 and ACN and normal water filling after repair.
In writingcode E1, measured inlet valve resistance, and the replacement valve or Aquastop part number if installed.
Check and repair the flowmeter or pressure switch circuit
What they doIf water enters the tub during the E1 inspection tree check, the technician inspects the wiring and operation of the flowmeter (on flowmeter models) or the 83/63 pressure switch, reconnecting loose terminals or replacing the faulty sensor.
They must show youthe inspected flowmeter or pressure switch connector and any replaced sensor part.
In writingflowmeter or pressure switch circuit test findings and the component replaced.
Verify drain pump operation (235 ohms) to prevent pressure switch trip
What they doThe technician checks the drain pump rotor for debris and measures its stator winding resistance (235 ohms ±15 ohms) so residual water does not remain in the sump.
They must show youthe unobstructed drain pump impeller and its ohm reading on the multimeter.
In writingdrain pump resistance reading, residue removal, and verification of a complete fill and drain cycle.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check that the water supply faucet is fully open and flowing
- Who:
- you.
- How:
- verify that the shut-off valve supplying the Midea dishwasher is turned fully open and check a nearby kitchen tap to confirm normal water pressure.
- Result that matters:
- ensuring the water supply is active and within the 0.04 to 1.0 MPa operating range.
- If the tap was closed or throttled:
- open it completely and restart the wash program.
- If the tap is fully open and household pressure is normal:
- inspect the inlet and drain hoses next.
- Evidence to keep:
- the position of the water tap and whether kitchen tap flow was normal when E1 occurred.

Inspect the water inlet hose and drain hose routing
- Who:
- you.
- How:
- check behind the dishwasher and under the sink that the inlet hose is not kinked or crushed and that the drain hose is hung properly without kinks.
- Result that matters:
- ruling out a pinched supply line or siphon drainage during the 4-minute fill phase.
- If a hose was kinked or hung improperly:
- straighten and hang it properly, then test a cycle.
- If both hoses are clear and properly positioned:
- unplug the appliance and check the inlet filter.
- Evidence to keep:
- a photo showing the routing of the inlet and drain hoses under the counter.

Clean the water inlet filter and internal sump filters
- Who:
- you.
- How:
- unplug the Midea dishwasher, turn off the tap, unscrew the water inlet hose catching any residual water drops to clean debris from the inlet filter, and check that the interior base filters are clean.
- Result that matters:
- removing scale or sediment that restricts water intake or blocks complete draining between fills.
- If sediment was blocking the inlet screen or sump filter:
- clean and refit them securely, open the tap, and test.
- If the filters are clean and E1 still sounds the 30-second alarm:
- turn off the water supply and request professional service.
- Evidence to keep:
- condition of the inlet filter mesh and whether water enters the tub during the first 4 minutes.

Technician inspection of inlet valve, flowmeter and pressure switch
- Who:
- qualified appliance technician with mains power disconnected.
- How:
- follow the Midea E1 inspection tree: measure inlet valve resistance between wires EV1 and ACN (approx. 3.4 to 4.8 kilohms), inspect the Aquastop hose if fitted, and test the flowmeter or pressure switch (83/63) circuit.
- Result that matters:
- isolating whether E1 is caused by a failed valve coil, a locked safety hose, a sensor circuit fault, or residual water from a blocked drain pump.
- If inlet valve or Aquastop resistance is open/shorted or the valve pole is stuck:
- reconnect or replace the valve or safety hose.
- If water enters the tub at 0.04-1.0 MPa but E1 persists:
- reconnect or replace the flowmeter, pressure switch, or main PCB.
- Evidence to keep:
- measured kilohm resistance of the inlet valve and test results for the flowmeter or pressure switch circuit.
Removing the bottom board or opening the PCB box exposes 220-240 V live terminals: qualified technician only with power unplugged.

What it means
In Midea dishwasher user and technical service manuals (including the MFD45S200 and MDWEB1004LS series), error code E1 means water filling exceeded the preset time: the inlet valve stayed open for 4 minutes without the flowmeter counting the required water quantity. When E1 occurs, the dishwasher stops other components, runs the drain pump until the flowmeter stays motionless for 2 minutes, and sounds the buzzer for 30 seconds. Code E1 alone does not prove that the inlet valve or PCB has failed.
Warnings and stop conditions
- Highsource verified
Always disconnect the dishwasher from the electrical outlet and shut off the water tap before unscrewing the inlet hose or performing maintenance.

Symptoms and causes
Probable causes · in order
- Closed water tap, restricted intake or pressure below 0.04 MPaCommon
A shut or partially closed faucet, a kinked supply hose, or household water pressure below the required 0.04 to 1.0 MPa range prevents the tub from filling within 4 minutes.
Evidence: Midea MFD45S200W.2-ES y MFD45S200X.2-ES manual del usuario de lavavajillas · Midea MDWEB1004LS-W dishwasher technical service manual
- Jammed inlet valve filter or improperly hung drain hoseCommon
Debris blocking the inlet valve filter mesh restricts the 2.5 L/min flow rate, while an improperly hung drain hose can siphon water out during filling.
Evidence: Midea MDWEB1004LS-W dishwasher technical service manual
- Faulty electromagnetic inlet valve, Aquastop hose or drain pumpPossible
A broken inlet valve coil, a locked Aquastop safety hose, or undrained water tripping the pressure switch early will prevent water admission and trigger E1.
Evidence: Midea MDWEB1004LS-W dishwasher technical service manual
- Flowmeter, pressure switch or main PCB circuit failureLess common
A loose wire connector or defective flowmeter or pressure switch prevents the controller from registering incoming water pulses.
