Maytag Dishwasher F8E1 Error: Heater fault — not heating
What Does Maytag Dishwasher Error Code F8E1 Mean? F8E1 on Maytag JetClean, PowerBlast, and MDB dishwashers means the heater circuit is not raising water temperature as expected during main wash or heated dry. The control monitors water temperature via the thermistor; if temperature does not climb within the allowed window, F8E1 is thrown. The fault […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A heater fault leaves dishes not sanitized. Do not continue cycles until resolved — water temperature is key to sanitization.
Can I reset the code?
Yes. Cancel cycle and power-cycle. Code clears temporarily but returns on next heated cycle.
When to stop immediately?
Stop if you notice: F8E1 persists after a power cycle, Visible damage to the heating element.
Symptoms You May Notice
Dishes come out not fully clean
JetClean cycles complete but water never reached target temperature; food residue remains on dishes.
Heated dry cycle leaves dishes wet
The heated dry phase does not generate enough heat; dishes stay wet at cycle end.
F8E1 shown partway through main wash
Cycle detects heating failure during the main wash phase and halts.
Water feels lukewarm mid-cycle
Opening the door mid-cycle reveals water that is barely warm instead of hot.
Possible Causes
Failed heating element
The exposed heating element at the bottom of the tub has burned out or has an open coil.
DIY PossibleFailed thermistor
The temperature sensor has drifted out of range or failed open.
Requires ProfessionalFailed heater relay on control board
Control board cannot energize the heater even with good element and thermistor.
Requires ProfessionalSafe Checks You Can Do
-
1
Inspect the heating element visually
Open the dishwasher. Remove the lower rack. The heating element is the horseshoe-shaped coil at the bottom of the tub. Look for burn marks, pitting, or a broken section.
A visibly damaged element is a near-certain failure. Test with a multimeter — should read 10–30 ohms across the terminals.

2
Run a water-only test cycle
Start a short Rinse cycle and feel the tub water at 10 minutes — should be noticeably warmer than cold tap water on a JetClean.
If water remains cold at 10 minutes, the heater is not working.
When to Call a Professional
Contact a qualified technician if:
- Element reads infinite ohms on multimeter
- Element reads good but still no heating in cycle
- Thermistor reading does not match actual water temperature
