Error codes · Midea · Dishwashers

Midea dishwasher error codes: most of them are the water — in, out, or on the floor of the tub.

A Midea dishwasher prints a short code on its display, and most of them are plumbing — a supply valve half open under the sink, a drain hose with no high loop, suds in the base. Find the code below, work the checks in order, and clear it with the reset in the strip above the table. The ones that need a technician say so.

Covers: 2019-and-newer Midea built-in dishwashers (MDT24H2, MDT24H3, MDT24P3, MDT24P5, MDF18A1, MDF24).

Before you clear it

Midea prints E codes (E1, E2) and letter codes on laundry (OE, LE); a code with no match here is the model's manual.

1

The code shows in the time display (E1, E3, E4, E6, Ed). A model with no display flashes a pattern of the cycle lights instead, and the light on the outer door flashes white and blue; the book's table turns the pattern into one of these codes.

2

The reset: hold Start for three seconds to cancel the running cycle (the dishwasher drains), then switch the dishwasher's breaker off for one full minute (most are hard-wired, with no plug to pull; one on a cord unplugs under the sink), switch it back on and start a Quick cycle.

3

Water and the drain are the install: the drain hose must rise in a high loop under the sink (or go through an air gap on the counter) before it reaches the disposal or the sink tailpiece, and a new disposal must have its knockout plug punched out. That plumbing is a licensed plumber's work.

4

The Control Lock (Ctl Lock) holds every button; its light is on while it is set. Press and hold Delicate and Quick together for three seconds to turn it off.

5

The model and serial plate is on the edge of the door — open it and look at the right side of the door panel or the frame of the tub.

Water in, water out, and the heat

Fill taking too long

What it means

The dishwasher waited for its fill and the water level never rose in time. Nine times in ten the water is not reaching the valve.

Check first
  1. The supply valve under the sink (a small lever or knob on the hot line) is fully open — a valve a quarter turn open fills so slowly the control gives up.
  2. The braided line to the dishwasher is not kinked where it bends up under the cabinet floor.
  3. The hot tap at the sink runs with normal pressure; a house filter that has clogged, or a well pump between cycles, stalls the fill.
  4. A new install: the valve under the sink was actually turned on after the hookup.
The fix

Open the valve all the way, straighten the line, reset and run a Quick cycle. If the valve is open and the pressure is good, the inlet valve on the dishwasher (behind the kick plate, where the line attaches) is not opening — a part.

Overfilled or water in the base

What it means

The float in the base pan under the tub lifted and stayed up for two seconds — too much water in the tub, suds, or a leak into the base. The dishwasher pumps out and stops.

Check first
  1. Turn the supply valve under the sink off. If the tub keeps filling with the supply off, the water is coming back through the drain hose — a disposal or a sink drain backing up, or a hose with no high loop.
  2. Dish soap or too much detergent — a tub of suds lifts the float. Run a Quick cycle with nothing in it and a cup of white vinegar if the last load foamed.
  3. Was the dishwasher just moved or tilted? Water left in the base from the last cycle lifts the float. Switch the breaker off, pull the dishwasher forward, tip it back on a towel with a helper and let the base dry.
  4. The door gasket — a chip, a flat spot at the bottom corners, or a rack pulled through it. The gasket is the seal the tub relies on.
  5. Under the sink: the supply and drain connections at the dishwasher's inlet are dry when you run a cycle and feel them.
The fix

Fix the high loop, the suds or the gasket, dry the base, reset and run a Quick cycle. A base that fills again with the gasket good and the connections dry has a leak inside — a hose off the pump, the sump seal — or an inlet valve that will not shut. Either is a service call.

Stop & call

A leak the gasket, the suds and the connections do not explain is inside the cabinet, and water that keeps rising with the supply off and the drain clear is a valve that cannot shut. Switch the breaker off, turn the supply off, and call it in — never a wait-and-see.

Water not heating

What it means

The water in the tub did not reach the temperature the cycle asked for in the time allowed. The heater under the sump, its relay or the sensor that reads it is the fault; the dishwasher pumps out and stops.

Check first
  1. The hot water at the kitchen sink is hot — run it until it is before starting the dishwasher, so the heater is not asked to warm a tub of cold water from scratch.
  2. The filter in the floor of the tub is clean (twist the cylinder out, rinse it and the flat screen under it); water that cannot circulate never reaches the heater.
  3. Reset (breaker off one minute) and run a Quick cycle; at the first pause, feel the water through the door — warm means the heater works and the first fill was simply cold.
The fix

Hot water at the tap and a clean filter clear a one-off. An E3 that returns with hot water going in is the heating element, its relay on the board or the temperature sensor — parts a technician replaces under the tub.

Stop & call

E3 that comes back with hot water at the sink is a service call. The dishwasher will not run a cycle without its heater; on a machine under warranty it is a warranty call.

Sensors, boards and the panel

E6#4
Service call
Code

Temperature sensor open

What it means

The thermistor that reads the water temperature is reading open — the control cannot see the heat, pumps out, and stops everything.

Check first
  1. Reset (breaker off one minute) and run a Quick cycle.
The fix

An E6 that returns is the temperature sensor or its connector under the tub — a part a technician replaces.

Stop & call

E6 after a reset is a service call. Write the code down, note the model and serial from the door edge, and file it.

Ed#5
Service call
Code

Boards not talking

What it means

The display board in the door and the main control under the tub lost communication for 20 seconds. A loose harness, or one of the boards.

Check first
  1. Switch the breaker off for five full minutes, switch it on and try a cycle.
  2. Was the dishwasher just installed or the door panel just worked on? The harness runs from the door into the base; a connector left half seated prints this.
The fix

An Ed that comes back is the harness between the boards or a board itself — a service call. Nothing to check at home beyond the reset.

Stop & call

Ed after a five-minute reset is a service call. Both boards are inside the cabinet.

Control Lock#6

Also printed as Ctl Lock

Code

Control Lock is on

What it means

Not a fault. Every button is held so a child cannot start or change the cycle; the Ctl Lock light is on.

Check first
  1. Press and hold Delicate and Quick together for three seconds until the lock light goes out.
The fix

The panel answers again. If the panel still ignores every press with the light off, cut the power for one minute.

Rinse Aid#7
Fix at home
Code

Rinse aid is low

What it means

Not a fault. The rinse aid dispenser in the door is empty or nearly so, so the dishes come out spotted and wet.

Check first
  1. Open the door, turn the rinse aid cap on the door counterclockwise, fill to the line with liquid rinse aid, and wipe any spill before closing — spilled rinse aid foams the next cycle.
The fix

The light goes out on the next cycle. If the dishes still come out wet, turn the dispenser's setting up a notch.

Warranty · When to file

When it's a warranty call

Every unit leaves with the manufacturer's full factory warranty. The codes below name a part inside the machine — once the checks have ruled out the install, the power and the hoses, call Midea's line with the model and serial, and text us if you want a hand with the claim.

All units are surplus inventory (open box, cancelled order, customer return, overstock, or minor scratch & dent). Every unit includes the manufacturer's full factory warranty. Please inspect thoroughly in person before purchasing — cosmetic imperfections or missing accessories are possible.

Still stuck?

Text us the model number and what it's doing — we'll point you at the next step.

A fix, a part, or a warranty call — the plate's model and serial plus one line about the symptom is all it takes to tell which.

These pages are educational. Every appliance is a little different — follow the manufacturer's manual and local code, and leave gas, water heater and 240V work to a licensed installer.
