Whirlpool Washer Error Code F35 in Fleming Island
F35 on a Whirlpool Duet-family washer is an analog pressure sensor error: the control can no longer trust its water-level readings. It almost always arrives holding hands with SUD — excess suds — because foam is what usually confuses this sensor first.
What error F35 means
The pressure sensor reports the tub's water level to the control as an analog signal. F35 sets when that signal is out of range or implausible. On these Whirlpool models there's a famous accomplice: suds. Foam in the sensor's air hose corrupts the pressure reading, so F35 frequently follows detergent overdosing — the sensor may be a victim, not a culprit, which is why the diagnosis starts with the suds question.
Fleming Island sits about 18 miles from Downtown Jacksonville, part of the wider metro — pros based across the city cover it on their regular rounds.
How urgent is it? If the no-detergent test clears it: no visit needed, adjust the dose. If F35 persists with the foam gone: book within the week, and avoid running unattended cycles meanwhile.
What causes error F35
An error code names the system that reported trouble — the diagnostic finds which of these is yours.
What you can safely check yourself
- Audit the detergent first, honestly: dose size, HE or not. If loads have been generous, run one empty hot cycle with NO detergent and see whether F35/SUD clear — foam takes a cycle or two to leave the hose.
- If the codes clear with the no-detergent test, the repair is a dosing habit (1-2 tablespoons for HE machines), not a part — the happiest ending on this page.
- If F35 persists on a machine with no foam present, note when it appears — start of fill, mid-cycle — and whether fill levels have looked wrong (too little or too much water) lately.
- Don't ignore a persistent F35: level sensing guards against overfill. A machine guessing at its water level eventually guesses wrong in the wet direction.
What a technician checks
Diagnosis separates victim from culprit: the air hose and dome are checked and cleared of foam and blockages, the sensor's signal is read against known water levels, and the board's interpretation is verified last. Sensors get replaced on measurements, not on the code's say-so.
Parts most often involved: pressure sensors and air hoses — and detergent math when the machine is the victim. Each is identified against your exact model number.

A local appliance repair professional who covers your area answers, runs the appliance, tests the systems the symptom points to, identifies the failed part by model number, and quotes one total for the complete repair — before starting.

Whirlpool Washer Error Code F35 in Fleming Island — questions
Why do F35 and SUD appear together?
Because they're one event seen twice: foam corrupts the pressure reading (F35) and the machine also detects the suds themselves (SUD). Together they're nearly a signed confession from the detergent bottle.
How much detergent should an HE washer get?
Far less than instinct says — typically 1-2 tablespoons of HE detergent for a normal load. Modern detergents are concentrated and HE machines use little water; the excess has nowhere to go but foam.
Does F35 mean the sensor is dead?
Only after the foam and hose stories are excluded. Replacing a sensor that's being lied to by a foam-filled hose is the classic F35 misrepair — the code returns with the next load, and someone has your money.
