I have an old washing machine from the 90s, likely to be ~25 years old (make and model: Zoppas Pratica PTX43).
The machine has been working fine up to about two months ago. More recently, however, I noticed that every wash cycle seems to be taking longer and longer.
The average wash cycle duration used to be 2 hours, now it exceed 3+ hours and seems on the increase.
- Cycles get stuck at intermediate areas (between one letter and the other, or at the start of one letter)
- Machine emits a humming noise for the duration of the 'stuck' phase
- If left unmanaged, this situation can go on for 30+ minutes
What I checked
- Ensured that the washing machine filter is clean
- Checked that both water intake and waste pipes are not bent
- I don't believe water intake is not getting water as the clothes are being washed
- Similarly the water is being drained so I do not believe the waste pipe is clogged
- The soap drawer is relatively clean/unclogged
What I do as workaround (i.e. to speed up the machine)
When I notice that the machine is stuck, I just manually move the program dial forward a notch, so that the machine moves on to the next action. This is despite the instruction manual advises never to do that. This manual action allows me to get a cycle duration down to a more acceptable time (i.e. 2-2.5 hours)
- Is this symptom linked to a known/predictable cause that a repairer can reasonably fix or am I better off getting a new machine?
- Is there any danger that this issue, combined with my disregarding the manual instructions not to manually move the program dial, is likely to lead to unexpected outcomes (e.g. some electrical short-circuit)?
