Hotpoint Dryer Error Code E64: Heating Element Open... | appliancefaults.com

Technical Background:

The dryer's Main Control Unit (MCU) monitors the heating element circuit. When the MCU detects an open circuit (no continuity) in the heating element, it triggers the E64 Error code. This typically indicates a break in the heating element coil, a faulty thermostat, or a wiring issue. The MCU uses voltage feedback from a thermistor to verify proper heating, if that voltage is missing, an error is thrown.

Symptoms:

The dryer runs but does not heat up. The clothes remain damp after a normal drying cycle. Error code E64 is displayed on the dryer's control panel.

Possible Causes:

Open heating element coil
Faulty heating element thermostat
Loose or corroded wiring connections to the heating element
Defective thermal fuse
Tripped thermal cut-off
Damaged wiring harness

Solution:

1

Disconnect the dryer from the power outlet. Verify the breaker is OFF in the breaker panel.
2

Locate the heating element housing, typically at the rear of the dryer. Remove the rear access panel using a 1/4-inch nut driver.
3

Visually inspect the heating element for any breaks or signs of damage to the coil.
4

Disconnect the wires from the heating element terminals.
5

Using a multimeter set to Ohms, test the resistance of the heating element. A good element typically reads between 8-12 Ohms. An open circuit (infinite resistance) indicates a faulty element.
6

Test the thermal fuse and thermostat for continuity. Replace if either shows an open circuit.
7

Reassemble the dryer and reconnect it to the power outlet.

Safety Warning:

Disconnect the dryer from the power outlet and verify the breaker is OFF before performing any repairs. Dryer circuits are 240V AC and can cause serious injury or death. Lock Out/Tag Out (LOTO) procedures must be followed.

Prevention:

Clean the lint filter after every load to prevent overheating. Annually inspect the venting system for obstructions and clean it thoroughly. Avoid overloading the dryer.

Expert Tip:

If the thermal fuse keeps blowing, suspect a blocked vent or a faulty motor. Check the blower wheel for obstructions and the motor windings for shorts. A common problem is a partially blocked vent restricting airflow to the element causing it to overheat and blow the thermal fuse.

Frequently Asked Questions

•What is the typical lifespan of a Hotpoint dryer heating element?

A dryer heating element typically lasts 5-10 years, depending on usage and maintenance. Frequent use or poor ventilation can shorten its lifespan.

•Can I repair a broken heating element coil, or do I need to replace the entire assembly?

It's generally recommended to replace the entire heating element assembly. Attempting to repair the coil is often unreliable and can be a fire hazard.

•What should I check if the dryer is still not heating after replacing the heating element and thermal fuse?

Double-check the wiring connections to the heating element and other components. Also, test the dryer outlet voltage to ensure it's receiving the correct 240V AC power. A voltage drop can cause insufficient heating.
