Speed Queen CHM1792C Washer Error Code E tE: Maximum Water Temp

What does Speed Queen error code E tE mean?

The CHM1792C watches the water temperature and has a ceiling it will not let the bath cross. When the water exceeds that maximum, the control stops the cycle to protect the load and the machine and shows E tE. The wash stops with the code on the display, and the water may still be hot when you reach it. The code shows on heater models and on any machine fed with very hot water. It gives you a few places to look: a water temperature sensor that reads too low, so the control keeps heating past the real limit, a heater output stuck on past the set temperature, a hot water supply running hotter than the machine allows, or a sensor input on the control that misreads the heat. A heater that stays on is the more serious case, because the water can keep climbing. For that reason the door lock holds, and the load is not handed back until the water has cooled.

Affected models and control systems

This page covers heater models and hot-fed machines of the CHM1792C family washer-extractor front-end control, 20 to 100 pounds. Other controls report sensor trouble with different codes.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• The cycle stops with hot water in the drum
• The door stays locked
• E tE appears on the display

Possible causes

Listed in Speed Queen's documentation

• A water temperature sensor that reads too low
• A heater output stuck on past the set temperature
• Hot water supply running hotter than the machine allows
• A sensor input on the control that misreads the heat

Other likely causes — what usually sits behind error code E tE on this control. A technician confirms which one it is before any part is replaced.

• A heater contactor with welded contacts that keeps the element energized after the control turns it off
• A building water heater turned up to a setting above what the machine accepts

Safe checks before calling for service

How a technician diagnoses error code E tE

1. Read the code and ask which formula and temperature were running.
2. Measure the temperature of the hot supply at the machine.
3. Compare the sensor reading with a calibrated thermometer reading of the bath.
4. Check whether the heater output turns off when commanded, including the contactor.
5. Replace the sensor, contactor or input only after it fails the test.
