If your automatic dishwasher fills more slowly than it did when first installed, it probably has a clogged inlet screen. Cleaning this tiny screen should speed things up.
Materials Needed: Masking Tape, Vinegar
Tools: Screwdriver, Slip-joint Pliers, Long-nose Pliers, Toothbrush
- Turn off the power to the dishwasher at the main panel or, if you have a portable dishwasher, unplug it.
- Turn off the hot water supply valve to the dishwasher under the sink.
- Remove the access panel (Figure A) at the base front of the dishwasher. It may rotate down, or you may have to remove several screws.
- Using slip-joint pliers, unscrew the hot-water-hose couplings at the inlet valve and at the water supply valve under the sink.
- Look for an inlet screen in either end of the hot-water-hose. If it's there, go to Step 7. If it's not there, it will be just inside the inlet; (Figure B)
- Label the wires on the inlet valve with masking tape to indicate their position. Then, pull the wires off the terminals with long-nose pliers.
- Carefully pry out the inlet screen with a small screwdriver.
- Clean the screen with a toothbrush and running water. If it is coated with mineral deposits, soak it in vinegar overnight and clean it again.
- Pop the screen back in and reconnect the hoses. Reattach the wires to the inlet valve and restore the power. Turn on the supply valve and check for leaks . Tighten the hose couplings as necessary.
