Purchased this model range in April 2023, upon using it we get a F022 error code. 
Called service number, 
First visit: tech came and reset the control panel,
2nd time we turned it on same problem F022 error
Second visit: had  to order a new control panel, none in stock, had to wait 2 weeks.
Third time we turned it on- guess what ran for 15 minutes, cut off with a F022 error code, now waiting on the tech to visit us for the fourth time in 3 months
