Midea Washer Error Code E33

E33 means the main control board is not receiving any signal from the water level sensor, also called the water level switch or pressure switch. This sensor tells the washer how much water is in the drum during a cycle. Without that signal, the washer stops operation to prevent overfilling or running a cycle incorrectly. The fault is typically caused by a wiring issue, a failed sensor, or a disconnected pressure hose.

No, it is not safe to continue running the washer while E33 is active. The control board relies on the water level sensor to regulate how much water enters the drum, and without that signal it cannot prevent the machine from overfilling. Continuing to run the washer in this state risks water damage to the appliance and your home. The fault should be diagnosed and resolved before resuming normal use.

Repair costs vary depending on what component has failed. If the fix is simply reseating a loose connector or repositioning a kinked hose, there may be no parts cost at all, though a service call from a technician could run anywhere from $75 to $150. Replacing the water level sensor typically costs between $15 and $60 for the part, plus labor if a technician is doing the work. A main PCB replacement is the most expensive scenario and can range from $100 to $300 or more for the part alone.

Start by checking the wire harness that runs between the water level sensor and the main PCB, looking for loose connectors, broken wires, or corrosion. Next, inspect the pressure hose connecting the tub to the sensor for kinks or detachment. If those components look fine, test the water level sensor itself for continuity and replace it if it has failed. If all components test good, the main PCB may need to be replaced.

A power reset, such as unplugging the washer for a few minutes and restarting it, may temporarily clear the E33 code if the fault was caused by a momentary signal interruption. However, if the underlying issue is a failed sensor, damaged wiring, or a disconnected pressure hose, the error will return as soon as the washer attempts to read the water level again. A reset is worth trying as a first step, but it does not fix the root cause.
