Hi i spoke to the customer on the phone and the washing machine beeps immediately its switched on and it comes up f37.
i looked on the site and on the bosch site where i downloaded the insructions but i van find no info.
any help welcome.
F37 is an NTC fault……is the machine in an outbuilding ? Maybe sited somewhere very cold ?
If it is , ask the customer to pour about a litre of warm water into the drum , leave for 30 seconds and then try it . It may be that the NTC has gone out of range .
If not , then you should be looking at he heater element and NTC.
