What Does Error Code E61 Mean on a Siemens Washing Machine?
Check and clean the filter, then run a short hot wash cycle (60°C or above) to confirm the heating element is working — if the water warms up and the cycle completes without E61 returning, a partial blockage was restricting flow to the heater (takes about 10 minutes).
Fault description
Error code E61 tells you that your Siemens washing machine has detected a problem with its heating circuit. The machine monitors water temperature throughout the wash cycle, and if the water fails to reach the target temperature within a set time window, E61 is triggered and the cycle is interrupted or abandoned.
The heating circuit includes the heating element itself, the NTC temperature sensor (which reads the water temperature), the wiring connecting these components, and the control board that manages the whole process. A fault in any one of these parts can produce E61.
When this error appears, you may notice that clothes come out cold or only slightly warm after a hot wash, or that the machine stops mid-cycle and displays the code on the display panel. The drum may still turn, but the water is not being heated as expected.
Causes
- Faulty or burnt-out heating element — The heating element is the most common cause of E61. Over time, limescale build-up or general wear can cause the element to fail, meaning it draws no power and cannot heat the water.
- Defective NTC temperature sensor — The NTC sensor monitors water temperature and reports back to the control board. If it gives an inaccurate or absent reading, the machine may think heating has failed even if the element is working correctly.
- Heavy limescale deposits on the heating element — In hard water areas, limescale can coat the heating element so thickly that it overheats and trips a thermal cut-out, or simply becomes too inefficient to raise the water temperature in time. This is particularly common in machines that have never been descaled.
- Wiring or connector fault — Loose, corroded, or damaged wiring between the heating element, the NTC sensor, and the control board can interrupt the circuit and trigger E61. Vibration over years of use can work connectors loose.
- Failed control board (PCB) — If the main PCB cannot send the correct voltage to the heating element or cannot interpret the sensor signal, E61 may appear even when the element and sensor are both in good condition. This is a less common cause but should be considered if all other components test correctly.
- Tripped thermal cut-out — Some Siemens models include a thermal cut-out fuse on the heating element that trips if the element overheats. Once tripped, it breaks the circuit permanently and must be replaced before heating will work again.
Step-by-Step Fix
- 1
Power cycle the machine
Switch the machine off at the mains and leave it unplugged for at least 5 minutes. Plug it back in, select a 60°C cotton cycle, and run it to see if E61 returns. Occasionally a temporary sensor glitch can trigger the code, and a full power reset clears it.
- 2
Clean the pump filter
A blocked filter can restrict water flow around the heating element, causing it to overheat and trip. Locate the filter behind the small access panel at the bottom front of the machine, place a towel and shallow tray underneath, unscrew the cap slowly, and clear any debris. Refit the cap firmly before running a test cycle.
- 3
Run a descaling cycle
If you live in a hard water area and have never descaled the machine, limescale on the element is a strong possibility. Add a proprietary washing machine descaler to the drum (follow the product instructions) and run the hottest cycle available. Repeat if the machine has not been descaled in over a year.
- 4
Inspect the heating element for continuity
Disconnect the machine from the mains. Access the heating element — usually located at the rear or front lower section of the drum, depending on your model. Disconnect the wiring connectors and use a multimeter set to resistance (Ω) mode. A healthy element typically reads between 20 and 50 ohms; a reading of zero or infinity indicates a failed element that needs replacing.
- 5
Test the NTC temperature sensor
With the machine still unplugged, locate the NTC sensor — it is usually clipped into the heating element housing or mounted nearby on the drum casing. Disconnect it and test resistance with a multimeter. At room temperature, most NTC sensors read between 10,000 and 20,000 ohms; consult your model's service data if available. A reading far outside this range points to a faulty sensor.
- 6
Check wiring and connectors
Visually inspect all wiring leading to the heating element and NTC sensor. Look for burnt insulation, corrosion on connector pins, or connectors that have worked loose. Push any loose connectors firmly back into place. If you find burnt or broken wires, these will need to be repaired or the wiring harness replaced before the machine is used again.
- 7
Replace the faulty component
Once you have identified the failed part — element, NTC sensor, or thermal cut-out — fit a genuine Siemens-compatible replacement. Reconnect all wiring carefully, reassemble the machine, and run a full hot cycle to confirm the fault is resolved and E61 no longer appears.

When to call a service technician
If you have tested the heating element and NTC sensor with a multimeter and both appear to be within normal range, but E61 continues to appear, the fault is likely inside the main control board (PCB). PCB diagnosis and replacement requires specialist equipment and knowledge of board-level electronics — this is not a safe DIY repair for most homeowners.
You should also contact a service technician if you find burnt wiring, signs of water ingress near electrical components, or if the machine trips your household circuit breaker when it attempts to heat. These symptoms suggest a more serious electrical fault that carries a safety risk if left unaddressed.

Frequently Asked Questions
Can I still use my Siemens washing machine while it shows E61?
It is not recommended. When E61 is active, the machine is not heating the water, which means laundry will not be properly cleaned or sanitised. Running repeated cycles without heat also puts unnecessary strain on the control board as it repeatedly attempts to trigger the heating circuit. Resolve the fault before using the machine for normal loads.
How do I know if my heating element has failed or just needs descaling?
A multimeter test is the most reliable way to tell. A failed element will show zero or infinite resistance, while a scaled-up element may still show a normal resistance reading but perform poorly in practice. If the element tests within range, try a descaling cycle first before replacing the part.
Is E61 the same fault on all Siemens washing machine models?
E61 consistently relates to the heating circuit across Siemens washing machine ranges, but the exact component layout and access points differ between models. Always check your specific model's user manual or service documentation before attempting any internal inspection, as drum access and element location can vary.
How much does it typically cost to fix an E61 error?
If you replace the heating element yourself, parts typically cost between £20 and £60 depending on the model. An NTC sensor is usually cheaper, often under £20. If you call a service technician, expect to pay a call-out fee plus labour on top of the part cost. A PCB replacement is significantly more expensive and may not be economical on an older machine.
Why does E61 appear only on hot wash cycles and not on cold washes?
Cold wash programmes do not activate the heating element at all, so a fault in the heating circuit will only become apparent when the machine tries to heat the water. If E61 appears exclusively on warm or hot cycles, this strongly points to the heating element, NTC sensor, or their associated wiring rather than a broader control board issue.
