Hi, welcome to Just answer
How old is it ?
The error code is 38 or 36 ?
E 38 error means sensing circuit of pressure switch is faulty...you will have to unplug the appliance and then take the top off the unit, there are two pressure switch which can be identified by a thin tube attached to them...take off the tubes and then blow as hard you can, make sure both hoses are clean and then with a screw driver give good tap on them so everything is cleaned...after this try to run a cycle, if the problem remains then it can be due to faulty pressure switch or a defective control board
E 39 error also means same HV sensing circuit of anti-overflow pressure switch faulty
so booth the error codes indicate problem with the pressure switch
