Midea Dishwasher E3 — What It Means & How to Fix It
Your Midea dishwasher isn't reaching wash temperature — E3 is the heating fault, and because it sits on the heater circuit it's a technician repair after a single reset.
What this code means
E3 on a Midea dishwasher means the water didn't reach the required temperature in time. That points to the heating element or its temperature sensor (thermistor). These live on the dishwasher's electrical heating circuit, so there's no owner-serviceable part — the only safe step you can take is a power reset.
Midea's user manual for the MDWEF1433G lists E3 as "Not reaching required temperature", with a malfunctioning heating element as the cause. If a reset doesn't clear it, the element or thermistor needs professional testing — not a DIY job, as it involves the heating circuit.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One-time control or sensor glitch | Common | Yes — power reset |
| Failed heating element | Common | No — technician job |
| Faulty temperature sensor (thermistor) | Common | No — technician job |
| Control board not reading the sensor | Less common | No — technician job |
What you can try yourself
- Switch the dishwasher off at the wall (or breaker) for five minutes, then restore power — this is the only fix to try yourself.
- Start a normal cycle and see whether E3 returns.
- If the code is gone, it was a transient glitch and no repair is needed.
- If E3 comes back, stop here and book a technician — the heating element and thermistor are on the heater circuit and aren't a safe DIY repair.
When to call a technician
- E3 returns after a power reset.
- Dishes come out cold and not properly cleaned or dried.
- The code followed a power surge.
Typical professional repair cost: Heating element or thermistor replacement on a Midea dishwasher typically runs $150—$320 including labor.
Frequently asked questions
Can I fix E3 on my Midea dishwasher myself?
Only the reset. The fault is on the heating circuit — the element or thermistor — which isn't owner-serviceable. If a power reset doesn't clear it, the repair needs a qualified technician.
Will the dishwasher still run with E3?
Some models finish the cycle without proper heating, so dishes come out cooler and may not dry well. Even if it runs, the heating fault should be diagnosed rather than ignored.
Why does heating need a technician when draining doesn't?
Drain and fill faults are usually hoses and filters you can safely reach. Heating faults sit on the electrical heater circuit, which carries higher current and isn't something to open up at home.
What does the E3 error mean on a Midea dishwasher?
E3 on a Midea dishwasher means the water didn't reach the required temperature in time, which points to the heating element or its temperature sensor. These sit on the heating circuit, so there's no owner-serviceable part — a power reset (off at the wall for a minute) is the only safe step before calling a technician.

Related Midea codes
- Midea Dishwasher E1 Your Midea dishwasher didn't take in water within the allowed time — E1 is the fill (inlet) timeout, usually a closed tap, kinked hose, or clogged inlet screen.
- Midea Dishwasher E4 Your Midea dishwasher detected too much water or a leak — E4 is the anti-flood (overflow) trip, so the first move is to shut off the water and dry the base pan.
- Midea Washer E1 Your Midea washer isn't getting enough water during fill — E1 points to the supply side (taps, inlet hose, mesh filter) far more often than to the machine itself.
- Midea Washer E2 Your Midea washer can't pump the water out — E2 flags a drain that didn't complete in time, usually a kinked or too-high drain hose or a clogged pump filter.
