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)
- Press the ‘On/Off’ button to pause the dishwasher cycle.
- Locate the water supply valve for the dishwasher, which is typically found under the kitchen sink.
- Check to ensure the valve is fully in the ‘On’ position by turning it counter-clockwise until it stops.
- Inspect the water inlet hose connected to the dishwasher for any sharp bends or kinks that could block water flow.
- Gently straighten the hose if you find any obstructions and confirm the error stays cleared during a full test cycle.
- If the issue persists, turn off the water valve, unscrew the hose, and check the small filter screen inside the connection for any debris. Clean it with a small brush under running water.
- Reconnect the hose securely, turn the water supply back on, and press ‘Start’ to resume the cycle.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Dishwasher
Bosch dishwasher symptom: Use the symbol or code as a starting point, then match the repair path to what the dishwasher is actually doing.
- Confirm whether the display is a normal cycle/status symbol or a recurring fault that stops operation.
- Check water supply, filter, sump, spray arms, drain path, and door latch before replacing electronic parts.
- If the same problem returns after basic checks, inspect the matching sensor, pump, heater, wiring, or control path based on the symptom.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
