The PS error on your Maytag Washer means the machine’s pressure switch (water level sensor) is not sending a valid signal to the control board. This usually points to a wiring, drain, or sensor problem rather than a serious mechanical failure, and many homeowners can check the basics themselves before calling a repair tech.

Error code PS
Meaning Pressure switch fault — the washer can’t confirm water level
Severity Medium — the washer may not fill, drain, or spin correctly until resolved
Time to fix 15–45 minutes
Tools needed Multimeter (optional), flashlight, screwdriver

What the PS error means

Maytag washers use a pressure switch to detect how much water is in the tub, which tells the control board when to stop filling, start agitating, or begin draining. When this code appears, the control board has either lost its signal from the switch or received a reading that doesn’t make sense — for example, showing water present when the tub should be empty.

This error is similar in nature to sensor-related codes like the Maytag Washer F1 Error Code: Causes and Fixes, where the control board can’t trust the data it’s getting from a key component.

Common causes

  • A kinked, pinched, or disconnected pressure switch hose
  • Water or moisture buildup inside the pressure switch air dome
  • A failed or corroded pressure switch
  • Loose or damaged wiring connector at the switch or control board
  • Drain hose issues causing incorrect water level readings
  • A faulty main control board (less common)

How to fix the PS error

  1. Power cycle the washer — Unplug the machine for 60 seconds, then plug it back in. This clears temporary faults and resets the control board.
  2. Check the pressure switch hose — Locate the small air hose running from the tub to the pressure switch (usually near the top of the cabinet). Make sure it isn’t kinked, cracked, or disconnected.
  3. Inspect for water in the hose — Remove the hose and check for condensation or blockage inside. Dry it out and reattach securely.
  4. Test the pressure switch — With power disconnected, use a multimeter to check continuity across the switch terminals. Replace the switch if it fails to show continuity when air is blown into the hose.
  5. Check wiring connections — Inspect the wire harness at both the switch and the control board for looseness, corrosion, or damage.
  6. Call a technician — If the switch and wiring test fine, the control board itself may need replacement — this is best handled by a qualified appliance repair professional.

FAQ

Can I still use my washer with a PS error?
It’s best to stop using the washer until the issue is checked, since incorrect water level readings can cause overfilling, poor rinsing, or draining problems.

Is the PS error the same as an F5 code?
No. The PS code relates specifically to the pressure switch, while issues like the Maytag Washer F5 Error Code: Causes and Fixes often point to the door lock or lid switch system instead.

Do I need a technician to fix this?
Not always. Many PS errors are caused by a simple hose blockage or loose connector, which homeowners can often fix themselves without special tools.
