Check the connector at the pressure switch. |

Unplug the pressure switch and read the resistance across terminals 1 and 3 (the outer terminals.) It should be 22 ohms ± 10%. If it is out of spec, replace it. Note there is an adjustment screw on the top of the switch. DO NOT adjust it. It is set at the factory and should not be altered. Any change can cause machine malfunction including fill errors, drain errors, and flooding. |

Check to see if the air chamber is clogged. (This could be lint or detergent build-up.) Before proceeding, it is probably a good idea to drain the sump of the machine. See PUMPS for more information. Pull the hose off the pressure switch and blow into it to see if there is blockage. If so, remove the air chanber from the tub by pulling off the small hose to the pressure switch and loosening the clamp on the other end of the air chamber. Remove the screw that attaches the air chamber to the tub, clean it, and replace it. DO NOT blow into the pressure switch. It will rupture the diaphram and destroy the switch. |

Check for leaks and verify the repair by putting the machine into test mode, opening a water valve, and watch the water level reading change on the display. |
