Washer shows E7 and may not detect correct water level; can overfill, underfill, or stop unexpectedly.

Safety first: Unplug the washer before removing the top or rear panel.

• Locate pressure sensor: On most Comfee washers, the water level sensor (pressure switch) is mounted near the top side wall with a small rubber hose running down to the tub or air chamber.
• Inspect hose: Check the thin pressure hose for kinks, cracks, or disconnections. Remove it from the sensor and gently blow through it to clear any soap residue or lint blockage.
• Check air chamber: Where the hose connects to the tub or air dome, ensure the port is not clogged with detergent sludge. Clean if necessary.
• Reconnect firmly: Reattach the hose securely at both ends and ensure the electrical connector on the pressure sensor is fully seated.
• Test cycle: Plug the washer back in and run a rinse/spin cycle to see if E7 clears. If the error returns, the pressure sensor itself may be faulty and should be replaced.
