Bosch Washing Machine E29 Error code (No water inlet)

How to unblock water inlet to machine

[@siouxseq549]

I am a carer with a load of washing to do. The washing machine is outside in a shed. E29. Hell. It'a 10th March 2023 in Scotland. Lo. It snowed. It's frozen. Now I know that E29 is the water inlet all I have to do is wait. I can't thank you enough.
