Probably due to Heater Relay on the main Control Module Board type problem (very common on these machines 🙁 ) Expensive to fix due to replacement component cost I’m afraid.
If your machine has an extended warranty I recommend getting it looked at by the relevant service agents 😉 I fear it will cause all the programmes problems in the near furture 🙄
Well, since I have no extended warranty, I guess I’ll be down to Currys this afternoon to get a new washing machine… Not an Ariston though, that’s for sure! 😡 Maybe a Bosch…
