What Does Error Code E61 Mean on a Bosch Washing Machine?
Check and clean the filter at the bottom front of the machine to rule out any secondary blockage affecting the heating cycle, then restart the programme — if the fault is a temporary sensor glitch, the machine should complete the cycle normally (takes about 5 minutes).
Fault description
Error code E61 points to a problem in your Bosch washing machine's heating circuit. This is the system responsible for warming the water to the temperature you've selected on the dial or display. When the machine detects that the water isn't reaching the right temperature within the expected time — or that the heating element is drawing incorrect current — it stops the cycle and displays E61 to protect the machine and your laundry.
When this error appears, the drum may stop mid-cycle, often with water still inside. The machine is not necessarily broken beyond repair; in many cases the fault is a worn heating element or a small temperature sensor that has drifted out of range. Both are relatively straightforward parts to replace. Understanding which component has failed will help you decide whether this is a DIY job or one for a service technician.
Causes
- Failed heating element — The heating element is the most common cause of E61. Over time, the element burns out or develops a break in the coil, meaning it can no longer heat the water. A simple continuity test with a multimeter will confirm whether the element has failed.
- Faulty NTC temperature sensor — The NTC (Negative Temperature Coefficient) sensor monitors water temperature and feeds that data back to the control board. If the sensor drifts out of its calibrated range or fails completely, the board may incorrectly conclude that heating has not occurred and trigger E61.
- Wiring or connection fault — Loose, corroded, or damaged wiring between the heating element, the NTC sensor, and the main control board can interrupt the circuit. Vibration over years of use can work connectors loose, causing intermittent or permanent faults.
- Scale build-up on the heating element — In hard-water areas, limescale accumulates on the surface of the heating element, insulating it and reducing its efficiency. Severe scaling can cause the element to overheat and fail, or cause the machine to time out before reaching the target temperature.
- Main control board fault — If the control board itself is damaged — through a power surge or component failure — it may misread signals from the heating circuit or fail to send power to the element at all. This is less common but should be considered if all other components test correctly.
Step-by-Step Fix
- 1
Reset the machine
Switch the washing machine off at the mains socket and leave it unplugged for at least 10 minutes. This allows any temporary sensor glitch or control board error to clear. Plug back in, select a programme with a heating cycle (e.g. 40°C cotton), and run it to see if E61 returns.

Clean the drain filter
A blocked filter can cause secondary issues that affect cycle completion. Locate the filter panel at the bottom front of the machine, place a towel and shallow tray underneath, and unscrew the filter cap slowly to drain residual water. Remove any fluff, coins, or debris, then refit the filter firmly.
- 3
Run a hot descaling cycle
If you live in a hard-water area and haven't descaled recently, add a proprietary washing machine descaler to the drum and run the hottest empty cycle available. Heavy limescale on the element can cause it to struggle or fail — descaling may restore normal function if the element itself is still intact.

Inspect and test the NTC temperature sensor
Disconnect the machine from the mains before doing this. The NTC sensor is usually located on the sump hose or near the heating element at the base of the drum. Disconnect its wiring plug and test resistance with a multimeter — at room temperature it should typically read around 10–20 kΩ depending on the model. A reading of zero or infinity indicates a failed sensor that needs replacing.
- 5
Test the heating element
With the machine unplugged, access the heating element from the rear of the machine by removing the back panel. Disconnect the element's wiring terminals and use a multimeter set to resistance. A healthy element typically reads between 20–30 ohms; a reading of zero (short circuit) or open circuit (no reading) means the element has failed and must be replaced.

Check wiring and connectors
While the back panel is off, visually inspect all wiring leading to the heating element and NTC sensor. Look for burnt insulation, corrosion on connector pins, or terminals that have worked loose. Gently press each connector firmly back into place. If you find burnt or broken wires, these will need to be repaired or the wiring loom replaced.

Replace the faulty component
Once you've identified the failed part — most often the heating element or NTC sensor — source a genuine Bosch replacement using your machine's full model number (found on the door frame label). Both parts are available as spare parts and can be fitted at home with basic tools, following the removal steps in reverse.

When to call a service technician
If you've tested both the heating element and the NTC sensor and both appear to be functioning correctly, the fault may lie with the main control board or with wiring that is difficult to trace without specialist diagnostic equipment. Control board faults are not straightforward DIY repairs — incorrect handling can cause further damage and the part itself is expensive.
You should also contact a service technician if you are uncomfortable working with the internal components of the machine, if the wiring shows signs of burning or heat damage, or if the error code returns immediately after fitting a new heating element or sensor, as this suggests a deeper electrical fault that needs professional diagnosis.

Frequently Asked Questions
Can I still use my Bosch washing machine with an E61 error?
It is not advisable to continue using the machine while E61 is active. The machine will typically stop mid-cycle and may leave clothes in cold or lukewarm water. Running repeated cycles with a faulty heating circuit can put additional strain on the control board and other components, potentially turning a simple repair into a more costly one.
How much does it cost to fix a Bosch E61 error?
If the fault is a failed heating element or NTC sensor, the parts themselves are relatively affordable — typically between £15 and £50 depending on the model. If you fit the part yourself, that's your total cost. A service technician call-out will add labour costs on top, but is worth it if the fault turns out to be a control board issue, which can cost significantly more.
How do I know if it's the heating element or the sensor causing E61?
Testing both with a multimeter is the most reliable way to tell them apart. The NTC sensor will show an out-of-range or open-circuit resistance reading if it has failed, while a faulty heating element will show either no continuity or a short circuit. If you don't have a multimeter, replacing the NTC sensor first is a reasonable starting point as it is the cheaper of the two parts.
Why does my Bosch washing machine show E61 only on hot washes?
If E61 only appears on programmes set to 60°C or above, the heating element is likely partially functional — it may heat water to lower temperatures but fail under the sustained load required for a hot wash. This is a common symptom of a heavily scaled or partially broken element. A descaling cycle may help temporarily, but replacing the element is the long-term solution.
Is E61 the same fault on all Bosch washing machine models?
E61 consistently refers to a heating circuit fault across Bosch washing machine ranges, but the exact component that triggers it and the location of parts can vary between models. Always check your specific model's manual or the model number label inside the door frame before ordering parts, as connector types and element specifications differ across the range.
