What F10 Means
WHICH MACHINES THIS APPLIES TO: F10 is a TD70-platform code and it belongs to the numeric-display variant of that platform, which Asko's service manual calls panel type B. The manual is explicit about how small the set is: "In the event of a problem, the CU can diagnose a number of parts and functions, and a total of 4 error codes can be displayed." F10 is one of those. The TD60 machines, the US T-series and the Logic and heat-pump E-series all report a full tank differently, so this page is for TD70 machines only. There is also an Asko dishwasher F10, which is an overfilling problem and has nothing to do with this one.
WHAT F10 MEANS: the service manual's cause column reads "The microswitch is opened when a full condensed water tank is detected. Detection begins 30 seconds after the program starts. If the microswitch is open >30 seconds the program cycle is stopped." Two timings are worth reading twice. The machine does not check at all for the first thirty seconds of a program, and it then requires the switch to stay open for more than thirty seconds before it acts. Neither a momentary bump nor the moment of starting will produce this code.
THE CUSTOMER CHECK ASKO PRINTS: "Emptied the tank and restarted the machine." That is the whole owner-facing procedure, and on a machine that simply needs emptying it is the end of the matter.
WHAT A TECHNICIAN IS ASKED TO DO IF EMPTYING DOES NOT CLEAR IT: the manual's service actions read "Clean hoses and check drainage pump voltage and resistance" and "Check that the float has not got 'stuck' and check the function of the microswitch." So the problem has two halves - a tank that really is full because the water is not being moved, and a tank that is not full but is being reported as full.
HOW THE FAULT INDICATION IS CLEARED: the manual gives one instruction for all the TD70 codes: "After carrying out corrective actions as above, reset the problem indication on the display by switching off the machine at the main power switch."
WHAT YOU MAY READ ELSEWHERE ABOUT THIS PLATFORM: one carefully written repair site publishes a set of TD70 dryer codes with the strings L2, L3 and L4, another set as S1 through S9, one called J1, and three called LCD1, LCD2 and LCD3. Those strings are not error codes. Each problem-indicator page in the TD70 service manual opens with a line drawing of the control panel, and every lamp, button and display on that drawing carries a reference designator on a leader line - L2, L3, L4, S1, S3, S4, S7, S9, S10, S11, J1 and LCD among them. S1 is the power button, S10 and S11 are start and stop, J1 labels the program dial indicator, and LCD labels the display itself. The actual problem table sits below the drawing, and it contains F10, F29 and F30 on the numeric panel, two lamp descriptions on the lamp panel, and plain-English messages on the TD70.2 and TD70.3 panels. The meanings attached to those invented strings are mostly real, but no owner will ever see L3 or S2 or LCD1 on a display, because they are labels on a drawing of the panel.
CLASSIFICATION: normal status when the tank is genuinely full. It becomes a problem only when the tank is empty and the machine still says otherwise.
Common Causes of F10
- Condensed water tank genuinely full
- Tank refitted but not seated fully, so the microswitch stays in the full position
- Float in the tank or the housing stuck, which the manual names directly
- Microswitch that detects the full condition failing
- Drainage pump not moving water to the tank or to the drain, which the manual asks a technician to check by voltage and resistance
- Hoses between the condenser and the tank blocked
🔧 One Safe Check You Can Try
Take the condensed water tank out, empty it, and put it back so that it seats fully and squarely - a tank that is nearly home can hold the microswitch in the same position a full tank does. Then switch the machine off at its main power switch, which is how Asko says to clear the indication, and start the program again. That is the complete published owner procedure. If the tank was not full when the code appeared, or if it comes back on the next cycle with an empty tank, the machine is not wrong about the switch but wrong about the level, and that is the float or the microswitch rather than anything you can correct. If the tank is filling far faster than it used to, or the machine is condensing very little, let it cool and clean the lint filter and the evaporator or condenser filter according to your model's manual before assuming a part has failed. Do not take the base or back panel off to look at the pump, the float or the switch: on this platform they sit alongside the drain pump and the mains wiring, and a heat-pump machine additionally holds a sealed refrigerant circuit that is not serviceable outside a workshop.
⚠ Why You Shouldn't Go Further Than That
- Emptying and refitting the tank is ordinary use and needs no precautions beyond the ones in your own manual.
- The drainage pump, the float housing and the microswitch sit in the base of the machine next to the mains wiring, so the dryer has to be unplugged or switched off at the breaker and drawn out before any of that is reachable.
- Heat-pump machines in this platform carry a sealed refrigerant circuit behind the same panels, and disturbing it is workshop work rather than a check.
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.
