Common Causes: Why Is My Washing Machine Not Heating Water?
Your washing machine relies on several parts working together to heat water. When any one of them fails, your clothes come out in cold water regardless of the temperature you select. Here are the 6 most common causes:
- Faulty Heating Element – The most common cause. The element burns out over time.
- Defective Thermostat – Regulates temperature; if it fails, heating stops at the wrong point.
- Failed NTC (Temperature) Sensor – Sends incorrect temperature readings to the control board.
- Damaged Wiring or Connections – Loose or burnt wires interrupt power to the heater.
- Control Board (PCB) Fault – The “brain” of the machine fails to trigger the heating cycle.
- Wrong Wash Program Selected – Cold wash cycles (e.g., 30°C Eco or Quick Wash) are intentionally cold.
Detailed Diagnosis & Repair Guide
1. 🔥 Faulty Heating Element
The heating element is a metal rod submerged in the drum that heats water directly. Like a kettle element, it burns out with regular use, especially with hard water.
Symptoms:
- Water is cold on all hot wash cycles (60°C, 90°C)
- Machine completes the cycle normally but clothes are not clean
How to Check:
- Unplug the machine from the power socket completely.
- Pull the machine away from the wall and remove the back panel (usually 4–6 screws).
- Locate the heating element — it’s a U-shaped metal bar at the bottom of the drum.
- Disconnect the wires from the element terminals.
- Use a multimeter set to resistance (Ω). Place probes on the two terminals.
- A reading of 20–50 ohms is healthy. An open circuit (OL/∞) means the element is burnt out.
Fix: Replace the heating element. Element costs in Kenya typically range from Ksh 1,500 – 3,500 depending on the brand (Samsung, LG, Bosch, Zanussi, Ramtons, etc.).
2. 🌡️ Defective Thermostat
The thermostat monitors water temperature and cuts off heating once the target temperature is reached. A faulty thermostat may cut heating too early — or not allow it to start at all.
Symptoms:
- Machine heats slightly then stops
- Some cycles heat, others don’t
- Overheating (rare) or under-heating
How to Check:
- Unplug the machine.
- Locate the thermostat — it is usually clipped onto or near the heating element.
- Remove it and test with a multimeter at room temperature. It should show continuity (close to 0 Ω).
- If it shows open circuit, the thermostat has tripped or failed.
Fix: Some thermostats are resettable (press the small button on the back). If it has tripped permanently, replace it. Cost: approximately Ksh 800 – 2,000.
3. 📡 Failed NTC Temperature Sensor
The NTC (Negative Temperature Coefficient) sensor is a small probe that tells the control board the exact water temperature. If it gives wrong readings, the board may think the water is already hot and skip heating.
Symptoms:
- Machine starts but never heats
- Temperature display shows incorrect readings
- Error codes related to temperature (e.g., E3, F3, tE1 depending on brand)
How to Check:
- Unplug the machine and locate the NTC sensor (usually attached near or alongside the heating element).
- Test with a multimeter on resistance mode.
- At room temperature (~25°C), a healthy NTC sensor reads approximately 10,000 ohms (10kΩ).
- As temperature increases, resistance should decrease — if resistance is wildly off or infinite, it’s faulty.
Fix: Replace the NTC sensor. Cost: approximately Ksh 500 – 1,500.
4. ⚡ Damaged Wiring or Loose Connections
Power surges (common in Kenya), vermin, and wear-and-tear can damage wiring to the heating element, cutting the power supply to it.
Symptoms:
- Machine was working fine, then suddenly stopped heating after a power surge
- Visible scorch marks or burning smell near the back of the machine
- Heating works intermittently
How to Check:
- Unplug and open the back panel.
- Visually inspect all wires running to the heating element and thermostat.
- Look for burnt insulation, melted connectors, or disconnected terminals.
- Gently tug each wire — loose connections will pull free.
Fix: Re-terminate or replace damaged wires and connectors. If the wiring harness is extensively damaged, professional repair is recommended.
5. 🖥️ Control Board (PCB) Fault
The PCB (Printed Circuit Board) is the electronic brain that controls all functions, including heating. If it is damaged, it may fail to send the signal to start the heating element.
Symptoms:
- Multiple functions fail at once (no heat + no spin, or no heat + error codes)
- Machine behaves erratically
- No response to temperature selection
How to Check: This requires professional diagnosis. PCB faults can sometimes be identified by burnt components or blown capacitors visible on the board. However, proper diagnosis requires specialized tools.
Fix: PCB repair or replacement. This is best handled by a qualified technician. Costs vary widely depending on the brand and whether the board can be repaired or must be replaced.

6. ✅ Check Your Wash Program First
Before assuming a fault, confirm you haven’t accidentally selected a cold cycle. Many modern machines have energy-saving programs that intentionally use cold or lukewarm water.
Common cold/low-temp cycles:
- Quick Wash / Express 15 or 30 min — usually cold or 30°C max
- Eco Wash — designed to save energy, uses lower temperatures
- Wool / Delicates — cold wash to protect fabrics
- Rinse & Spin — no heating at all
Fix: Select a Cotton 60°C or Cotton 90°C cycle and confirm the machine heats up. If it does, there’s no fault — just a program selection issue.
