Hotpoint Washer Dryer: temperature sensor error

Professional Repair Guide

What is this symptom?

Experiencing a temperature sensor error (F13) on your Hotpoint Washer Dryer? This issue prevents proper drying as the machine cannot read or regulate temperature accurately. It often displays an error code, indicating a fault that affects drying performance. Understanding the potential causes can help you troubleshoot effectively.

Urgency: Medium

Important Tips for Hotpoint Models

  • F13 error code on Hotpoint washer‑dryers specifically indicates a dryer temperature sensor or heating fault; official documentation recommends professional engineer resolution.

Possible Causes

Faulty dryer temperature (NTC) sensor

How to Identify: Error F13 on display during drying; sensor resistance out of expected range or open/short circuit when measured with a multimeter at room temperature. (

Part: Dryer NTC/temperature sensor

Dryer heater element or heating circuit fault

How to Identify: Dryer fails to heat even without error code; continuity test of heater shows open circuit; associated error codes sometimes accompany F13. (

Part: Dryer heater/heat element

Restricted airflow / blocked ducts

How to Identify: Reduced airflow, longer drying times; lint buildup visible in ducts/filters; error appears after heat buildup. (

Part: Dryer air duct/vent

Wiring fault between sensor and control board

How to Identify: Intermittent error, visible damaged insulation or loose connectors between sensor and main control board. (

Part: Internal wiring harness

DIY Solutions

Clean lint filters and dryer airflow paths

Easy 15–30 minutes
Tools Needed: screwdriver (model dependent)
  1. Unplug the washer‑dryer from power.
  2. Remove and clean all lint filters.
  3. Inspect and clear any visible lint or debris from the dryer air duct and vents.
  4. Reassemble and test a short dry cycle to see if error persists.
⚠️ Safety First: Ensure unit is fully powered off before opening any panels.

Check and test the dryer temperature sensor

Advanced 30–90 minutes
Tools Needed: multimeter, screwdrivers (Philips and possibly Torx)
  1. Unplug the appliance and allow all components to cool.
  2. Remove back panel or top cover to access the dryer heater assembly (model specific).
  3. Locate the temperature/NTC sensor on the heater housing or air duct.
  4. Disconnect and test the sensor’s resistance with a multimeter; compare reading to expected range (model specs).
  5. If sensor is open/shorted or outside expected range, replace sensor with correct part and reassemble.
⚠️ Safety First: Disconnect power before internal access; avoid damage to seals and wiring.

Professional Repairs

Replace dryer temperature sensor or heater assembly

Estimated Cost: $50–$200

Inspect and repair wiring harness or control board interface

Estimated Cost: $100–$300

When to Call a Professional

Error persists after cleaning airflow and replacing sensor.
Sensor values test out of range or heater element shows open circuit.
Wiring or control board faults suspected.

Preventive Maintenance

  • Regularly clean lint filters and dryer ducts: Overheating and airflow restricted errors that could trigger temperature sensor faults
    Frequency: monthly
  • Inspect visible wiring and connectors: Loose or damaged wiring causing intermittent sensor errors
    Frequency: annually

Common Issues Reported by Users

  • Faulty temperature sensor
  • Blocked condenser unit
  • Wiring issues or loose connections

User Suggested Solutions

  1. Inspect and replace the temperature sensor. First, disconnect the power. Locate the temperature sensor, usually found near the heating element. Remove the old sensor and replace it with a new one. Reconnect the power and test the machine.

  2. Clear the condenser unit. Disconnect the power and remove the condenser cover. Clean out any fluff or debris that may be blocking airflow. Reassemble the unit and test the washer dryer.

  3. Check wiring and connections. Disconnect the power and inspect the wiring harness connected to the temperature sensor. Look for any signs of damage or loose connections. Repair or replace as necessary.
