Midea EH0E error code

What it means

EH0E means the indoor unit thinks condensate water level is unsafe or the water-level alarm circuit is not reading correctly. Do not ignore it because water can overflow from the indoor unit.

Urgency

Likely causes

1. Brief power event, brownout, or unstable supply voltage
2. Loose power connection, reactor, or outdoor electrical component problem
3. Inverter/IPM protection or current-detection fault
4. Compressor winding, drive, or outdoor board fault after power checks pass

Homeowner fix

Turn the unit off to prevent overflow. If you have an external condensate pump with a visible reservoir, make sure it has power and is not obviously full or blocked. Do not open the indoor cabinet. Restart once only if no water is present.

When to call a pro

Call a licensed HVAC technician if water is present, the alarm returns, or the drain/pump is not plainly external and accessible. Tell them the code is EH0E water-level alarm.

Repair vs replace

This is normally a repair diagnosis, not an automatic replacement signal. If a technician confirms a major board, compressor, fan motor, or refrigerant-circuit repair on older out-of-warranty equipment, compare the quote with replacement.

For your technician

Technician note: section 7.4.1.9 lists wiring mistakes, water-level switch, water pump, and indoor PCB for the water-level alarm. Page context: Midea maps this display to the Advantage Series Multi-Zone line; source: Midea D5CMRA Installation Instructions Table 20 and shared ACiQ/Midea Multi-Zone Service Manual; display convention: match the letter E, letter H, zero, and letter E marker exactly before comparing neighboring codes.

Which systems show it

• Midea Advantage Series Multi-Zone D5CMRA R-454B outdoor condensers and matched indoor units covered by Table 20.
• Midea Advantage Series Multi-Zone High-Heat D5CMHA systems where the D5C installation/error-code convention is shared.
• Midea current R-454B single-zone high-wall families when the indoor display uses the same EC/EH/EL/PC homeowner code convention.

Sold under more than one brand

Also sold as ACiQ. Midea and ACiQ document this code from the same manufacturer source, so EH0E means the same thing on either badge and the steps above apply.
