Midea Washer Error Code E34

E34 on a Midea washer means the temperature sensor on the water heater is reading as an open circuit, indicating a broken electrical connection in that sensor loop. The control board cannot receive temperature data from the heater sensor, so it disables the heater as a safety measure. The washer will otherwise continue to run normally through its wash, rinse, and spin functions.

A simple reset will typically clear the displayed error temporarily, but E34 will return as soon as the washer checks the heater temperature sensor again and detects the open circuit. The underlying fault in the sensor, wiring, or connector must be resolved for the code to stay cleared. Resetting without repair is not a long-term solution.

Repair costs depend on which component has failed. If the issue is a loose or corroded connector, there may be little to no parts cost, though a service call can range from around $75 to $150 depending on your area. A replacement temperature sensor typically costs between $15 and $50 for the part alone. If the control board is at fault, parts and labor combined can range from $150 to $350 or more.

Yes, the washer will continue to operate normally with E34 active, but the internal water heater will not turn on. Cycles that rely on heated water, such as sanitize or high-temperature wash programs, will run without heat and may not achieve the intended cleaning results. For everyday cold or warm water cycles that use the home hot water supply rather than the internal heater, you may notice little difference in performance.

Running the washer with E34 active is generally safe because the control board has already responded to the fault by disabling the heater. There is no risk of the heater overheating since it is not operating. However, leaving a known electrical fault unaddressed for an extended period is not recommended, as wiring or connector issues can sometimes worsen over time.
