What TEMPERATURE STOP FAULT Means
WHICH MACHINES THIS APPLIES TO: Asko's professional washers - the WMC-series machines installed in communal laundry rooms, care homes, salons, gyms and small commercial laundries - do not report problems as numbers. They print the problem on the display in words. Two document families stand behind the messages on this site and they are deliberately kept apart, because they are not the same book and they do not use quite the same wording.
THE OLDER PLATFORM: the Asko service documentation for the new generation of washing machines whose circuit diagrams are labeled WMC55. Its problem section states that if a problem occurs during a program cycle it is shown on the display after the program has finished or been interrupted - which is worth knowing, because on this platform the message often appears at the end rather than at the moment something went wrong.
THE LATER PLATFORM: the operating instructions for the WMC64P and the WMC743VS, which both state that a message is shown on the display if an error occurs during the program. The message set in those two books is identical to each other, which is good corroboration of both.
A LIMIT WORTH STATING: no public document could be found under the model numbers WMC6743 or WMC6744. The messages here are attributed to the books they were read in and are not claimed to cover those models.
ONE PRACTICAL NOTE BEFORE ANY CHECK: a professional washer is usually hard-wired rather than plugged in, so isolating it means the breaker or the wall isolator that feeds it, not a plug. And in a communal or commercial room the machine belongs to somebody else. If that is your situation, the checks below are for the person who looks after the machines, and reporting the exact wording on the display is the most useful thing a user can do.
WHAT IT MEANS ON THE WMC55 PLATFORM: the problem list reads "Temperature stop problem. Check the fuses and the heating element. The washing program has finished without heating." Asko is doing two things in that entry - naming the two places a technician looks, and telling you what happened to the load.
HOW IT DIFFERS FROM THE THERMISTOR MESSAGE ON THE SAME MACHINE: both end with a wash that has not been heated, and that is why they are easy to confuse. The difference is what reported. A thermistor problem is the sensor circuit being wrong. A temperature stop problem is the temperature not rising as it should while the sensor is still reporting - which is why Asko sends you to the fuses and the element rather than to the sensor.
WHAT THE MACHINE WAS DOING: heating, or trying to. A washer monitors how the water temperature climbs during the heating stage. When it does not climb the way it should, it abandons heating and finishes the program rather than standing still, which is why this message tends to be read after a load has already come out.
WHY IT SHOWS UP AT THE END OF THE CYCLE: on this platform a problem during a program is displayed after the program has finished or been interrupted. Nobody was told at the time. That is worth knowing in a busy room where several loads may have gone through before anyone read the screen.
ONE INSTALLATION CAUSE WORTH RULING OUT IN A COMMERCIAL ROOM: a professional machine may be fed through a three-phase supply or its own dedicated circuit, and a single blown fuse or a tripped protective device can take the heating out while everything else on the machine still works. Asko naming the fuses first is not an accident.
CLASSIFICATION: problem. No owner repair is published, but the consequence for the laundry is immediate.
Common Causes of TEMPERATURE STOP FAULT
- Heating element failed or open circuit
- Fuse or protective device on the heating supply blown or tripped
- Wiring or connector to the element damaged
- Control unit or its relay not switching the element
- Machine plumbed to a supply and program combination where the water never needs to heat, masking the real behavior
🔧 One Safe Check You Can Try
Deal with the laundry first and the machine second. Any load that ran while this message was appearing was washed without heating, so in a care, food, salon or gym setting those loads need doing again once the machine is fixed - that is the part nobody else can do for you. Then gather what a technician needs: whether the message appears on every program or only on the hot ones, whether it started after work on the room's electrical supply, and whether anything else in the room lost power at the same time. Look at the machine's own supply protection if you are the person responsible for the installation and you are competent at the board - a tripped device or a blown fuse on the circuit that feeds the heating is exactly what Asko's first instruction points at, and it is a board-level check rather than a machine-level one. Beyond that, stop. Testing a heating element means isolating the machine at its breaker or wall isolator, opening the cabinet and working at terminals that are live whenever the machine is fed, and on a professional installation there may be no plug to pull at all.
⚠ Why You Shouldn't Go Further Than That
- Asko names the fuses and the heating element as the places to check, and both are electrical work behind a panel on a machine that is isolated at a breaker or wall isolator rather than unplugged.
- Element terminals are live whenever the machine is fed, and a professional installation may be on a dedicated or three-phase circuit that a room user cannot safely identify.
- A commercial machine may be bolted in place or plumbed in a run with others, so it is not simply drawn out for access.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
