Washing Machine Touch Pad
Installed the above in June 2021, ( Zanussi ZWF7254B4PW) it has a rotary programme selector switch plus 4 or 5 touch selections for Stop/Start, Temperature, Spin Speed, Delayed Start etc. I have to get a hair dryer and direct hot air onto the panel or a minute or less to get these to respond (every 3 months or so) apart from the Stop/Start which allways works consistently. The machine is in a unheated garage. Is this a common occurance?.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Zanussi ZWF7254B4PW touch keys unresponsive in cold garage
- The problem
- On a Zanussi ZWF7254B4PW installed in an unheated garage, the touch selections for temperature, spin speed and delayed start intermittently stop responding every few months. The start/stop touch key continues to work. The affected keys respond again after warming the keypad area with a hair dryer for under a minute, or by holding a hand over the keypad for about 5 seconds.
- Likely cause
- The discussion strongly suggests a temperature-related issue affecting the touch keypad area, with cold conditions in the garage likely causing contraction or loss of proper contact. This was diagnosed from the fact that local warming restores operation. The exact failed component or repair was not confirmed.
- What fixed it
- No repair was documented. The accepted advice was that very cold garage temperatures can adversely affect appliances, and the behaviour points to a cold-related keypad or connection issue. Exact repair was not confirmed.
- Checks to try
- Confirmed the non-start touch keys worked again after brief warming with a hair dryer
- Confirmed the keypad also worked again after warming with a hand for about 5 seconds
- Observed adjacent keypad temperature at about 12.5C
- Noted that the separate start/stop touch key was consistently unaffected
- Parts or tools mentioned
- Hair dryer
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello John. I couldn't say if there is a common fault on these touchpads, as I have not had anyone else mention a problem with them.
It is possible that the very cold temperatures in a garage can adversely affect appliances. Maybe something is contracting and no longer connecting or working properly. Heating it up directly appears to strongly imply that.
Unfortunately, garages are not a great place to have a washing machine. Make sure your pipework is all fully insulated too. My washing machine has always been in our garage, and about 10 years ago the water tap froze and popped off. When the water thawed out, it flooded our entire garage.

Found out that placing the palm of my hand across the keypad for 5 secs or so works as well, temp adjacent to the keypad is ~ 12.5C just now.
The stop/start is not part of the above so thats why i never had a problem with it even though its still a touch key.
Hi John. It looks like it definitely related to temperature. Something must be contracting and losing contact when it gets really cold.
