Washer displays F27 and may overfill or underfill, sometimes with erratic water levels.

Safety first: Unplug the washer and turn off the water supply.

Step-by-step checks:

• 1. Inspect pressure hose: Remove the top panel and locate the small hose running from the tub to the pressure switch. Check for splits, disconnections, or soap buildup. Clean or replace as needed.
• 2. Check for air leaks: Ensure the hose is tightly fitted at both ends and not rubbing against sharp edges.
• 3. Test pressure switch: Disconnect the switch and measure continuity across its terminals while gently blowing into the hose port. Contacts should change state as pressure increases.
• 4. Recalibrate (if model supports): Some Admiral models allow for water level calibration in diagnostic mode (refer to the tech sheet). Run this procedure after repairs.

When to call a technician: If the pressure system is intact but F27 persists, the main control may need replacement.
