What TEMPERATURE STOP FAULT Means
WHICH MACHINES THIS APPLIES TO: Asko washers with a text window rather than a numeric display report their problems in words. The Use and Care Guides for the US W6761, W640 and W660 carry one such table; the operating instructions for the W8844XL and the W6884 Eco carry another; and the WM60 service manual carries the problem-indication tables for the WM60.2 and WM60.3 panels. The wording varies between them, and the section below says which document each form comes from. All of these machines clear the message the same way, by turning the machine off and then back on.
WHAT ASKO PRINTS FOR THE OWNER: the W6761, W640 and W660 guide gives "Call a service technician."
WHAT THE SERVICE MANUAL ADDS: the W600-series service manual reads "The washing program has finished without heating. Check the fuses and the heating element." Two things follow from that sentence. The program completed - the machine did not stop dead - and the heating stage is the part that did not happen.
WHY THAT IS EASY TO MISS: the wash looks entirely normal. The laundry is clean, the cycle ran, the door opened, and the only thing missing is the temperature. People often notice the message before they notice that the clothes were cold, and quite often notice neither for several loads.
WHAT THE CONTROL IS JUDGING: it switches heating on and watches the temperature sensor, expecting a rise. When the rise does not arrive the way the program requires, it abandons the heating stage and carries on with the rest of the cycle. So this message is the outcome rather than the cause, and it covers the element, the relay that switches it, the supply and the sensor between them.
THE RELATED MESSAGE IN THE SAME TABLE: "Thermistor problem" reports the sensor specifically. This one reports that the water did not get hot without saying which part of the chain is responsible. Which of the two a machine shows is worth noting exactly, because they are investigated differently.
WHY ASKO'S SERVICE NOTE MENTIONS FUSES FIRST: because a lost supply is the cheapest possible explanation and the one to eliminate before anything is opened.
CLASSIFICATION: problem, on the heating side, with the program still completing.
Common Causes of TEMPERATURE STOP FAULT
- Heating element failed or open circuit
- Heating relay on the control not closing
- Supply to the machine interrupted, or a breaker or fuse gone
- Temperature sensor never confirming the rise
- Hot supply turned off on a machine plumbed for a hot fill
- Wiring or connector in the heating circuit
🔧 One Safe Check You Can Try
There is no owner repair, but there are two things worth establishing before anyone comes, and both are free. First, confirm the pattern: run a cold program and a hot one and note whether the cold one completes normally and the hot one produces the message. If cold washes are fine, the heating chain is confirmed as the area without a single panel being removed. Second, look at the supply, which is what Asko's own service note puts first. Check the breaker for the washer at the panel; reset a tripped breaker once and, if it trips again, leave it off and have the circuit looked at rather than resetting it repeatedly. Check too whether the machine was ever plumbed to a hot supply that has since been shut off, because a machine relying on hot water that is no longer arriving behaves almost exactly like one with a failed element. Then stop. The heating element terminals are inside the cabinet at mains potential whenever the machine is connected to power, the relay that switches them is on the control board, and reaching either means dismantling around a spring-suspended drum.
⚠ Why You Shouldn't Go Further Than That
- The element terminals are at mains potential whenever the machine is connected to power and they sit inside the cabinet, so nothing is opened until the machine is isolated at the outlet or the breaker.
- Reaching the element on a front-loading washer means working around a spring-suspended drum, which is a strip-down rather than a check.
- A breaker that trips again after one reset is reporting a problem on the circuit, and repeatedly resetting it puts current back through whatever caused it.
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.
