Electrolux Dryer: rumbling noise and error code E71

Professional Repair Guide

What is this symptom?

If your Electrolux Dryer is producing a rumbling noise and displaying error code E71, you may be experiencing issues with the thermistor, loose wiring, or worn mechanical components. Addressing these problems promptly can ensure your dryer operates efficiently and safely.

Urgency: Medium

Important Tips for Electrolux Models

  • E71 code specifically refers to outlet thermistor error (thermistor resistance out-of-range) on Electrolux dryers.

Possible Causes

Thermistor (outlet thermistor) fault

How to Identify: E71 error code specifically indicates thermistor resistance out-of-range or open circuit detected by dryer electronics.

Part: Outlet thermistor (temperature sensor)

Loose or damaged wiring between thermistor and control board

How to Identify: Intermittent error code E71 and possible noise if wiring harness is loose or damaged; visual inspection may show frayed or disconnected wires.

Part: Thermistor wiring harness

Control board malfunction

How to Identify: Persistent E71 error after checking thermistor and wiring, dryer controls unresponsive or erratic behavior.

Part: Main control board

Worn or damaged mechanical components causing rumbling noise

How to Identify: Noise during tumbling unrelated to error code; rumbling, grinding or thumping sound, drum may not spin smoothly by hand.

Part: Drum rollers, bearings, blower wheel, drive belt, idler pulley

DIY Solutions

Check and test thermistor and wiring

Advanced 30-60 minutes
Tools Needed: multimeter, screwdriver set
  1. Unplug dryer from power.
  2. Access outlet thermistor (consult manual for location).
  3. Inspect wiring harness for loose connections or damage.
  4. Measure thermistor resistance with a multimeter; around ~5,000 Ω at room temperature is normal.
  5. If resistance out of range or open circuit, replace thermistor.
  6. Reconnect wiring securely and test dryer.
⚠️ Safety First: Always disconnect power before accessing internal components.

Inspect and replace worn drum support rollers or bearings

Moderate 1-2 hours
Tools Needed: socket set, screwdrivers, work gloves
  1. Disconnect power to dryer.
  2. Remove dryer cabinet panels to access drum rollers.
  3. Manually spin drum; if it doesn’t rotate smoothly, remove and inspect all support rollers.
  4. Replace worn rollers and bearings with model-specific parts.
  5. Reassemble dryer and run an empty cycle to verify reduced noise.
⚠️ Safety First: Ensure dryer is fully disconnected from power.

Check and clear debris from blower wheel

Moderate 30-60 minutes
Tools Needed: screwdrivers, vacuum
  1. Unplug dryer.
  2. Remove access panel to blower housing.
  3. Inspect blower wheel for lint or items and remove obstruction.
  4. Ensure blower wheel spins freely; replace if damaged.
  5. Reassemble and test dryer noise.
⚠️ Safety First: Disconnect power and avoid touching sharp edges inside blower housing.
