How to Fix Bosch Dishwasher Error CHECK WATER LIGHT

Error Code: CHECK WATER LIGHT Difficulty: Easy

Problem: Indicates a problem with the water supply, such as a blockage or the tap being turned off.

How to Fix CHECK WATER LIGHT Error (Step-by-Step)

1. First, locate the water supply valve for your dishwasher, which is typically found in the cabinet under the kitchen sink.
2. Check the valve to ensure it is in the fully open position. The handle should be parallel to the water pipe.
3. Inspect the water inlet hose that runs from the valve to the dishwasher. Look for any sharp kinks or bends that could be restricting water flow.
4. Gently straighten any kinks you find in the hose to allow water to pass through freely.
5. If the valve is open and the hose is straight, turn off the water supply valve completely.
6. Place a towel under the hose connection at the valve and carefully unscrew the hose.
7. Look inside the connection for a small screen filter. If it is clogged with sediment, gently remove it and rinse it clean under a faucet before reinstalling it and reattaching the hose.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.
