condenser blocked? it was tried with clothes in was`nt it?? coz it does something similar if does not sense humidity.
have had a few with badly blocked (never cleaned!) condenser units.
Cupboard dry is NTC 2 overheat i think. This is the NTC situated at the back in the heater area. It’s worth checking the heater as i had a similar Bosch appliance doing the same thing but all airways were clear. Found the heater badly degraded with metal filings all over the back where the heater coil was falling apart- fitted new heater and hey presto! overheat fault disappeared too , prob because the NTC was in the same area.
