The sud flashes on the display. Have cleaned filter and hoses, did afresh several times. The door locks, machine pumps out, very little then the sud comes on. After it pumps out, very little water, the F35 code shows up. What should I check next? We are 1 1/2 hours from any repairman, any help would be greatly appreciated. Thank You
The F35 error code indicates that the Analog pressure sensor failure. The Central control unit has detected a malfunction in the pressure sensor. You will want to make sure that the pressure hose is attached properly and without holes or damage. Check to make sure that the air trap is not blocked. You will want to check to make sure that the drain hose, drain pump and hose from drain pump to the bottom of tub are clear without obstructions. If they get obstructed then it would cause this type of issue and would cause a sud issue. The drain pump may be thinking it is pumping bubbles instead of water and goes into suds lock.
What exactly is an airtrap? #2-What is the purpose of the ball and is there any distinct sound when there is a problem within the housing where the ball is located?
Answer Hello Steve,
The airtrap actually prevents any suds from getting into the pressure switch. It is an area where, if suds get into it, the suds will have to pop instead of interfering with the pressure switch operation.
The ball is located in the outer-tub-to-pump hose. The purpose of the ball is to keep foreign objects and debris from getting into the pump impeller. It makes no noise but if there is an issue in the drain hose, the unit will not drain.
