The Bosch dishwasher Check Water light shows a water supply problem. This warning means your dishwasher can’t fill or drain water properly. Many users fix this at home by checking hoses, filters, and water pressure.
What Does Bosch Dishwasher Check Water Light Mean?
The Check Water light on Bosch dishwasher signals a water flow problem. Bosch made this light to warn users about blocked hoses, clogged filters, or leaks. Most people fix this by cleaning filters or checking the water supply line.
Common Reasons for Bosch Dishwasher Check Water Light
1. Blocked or Kinked Inlet Hose
The inlet hose brings water into the dishwasher. People often find the hose kinked or blocked behind the machine. I once fixed my dishwasher by pulling it out and straightening the hose. Preventing bends keeps the water flowing properly.
2. Low water pressure
The Bosch dishwasher Check Water light often appears when water pressure drops. Homeowners should check tap flow by filling a bucket for one minute. If water flows slowly, you might need a plumber. I learned this after a frustrating night with dishes piling up.
3. Clogged inlet filter
The inlet filter collects dirt from hard water. Many users forget this part until the dishwasher shows errors. Cleaning it every few months keeps the water flowing smoothly. I cleaned mine and noticed faster wash cycles.
4. Activated Leak Protection System
Bosch added a leak protection system to prevent floods. When the base tray fills with water, the system shuts off the dishwasher. I tilted my machine back and drained the water to fix this. Regular checks can stop future leaks.
5. Blocked Drain Pump
The drain pump removes dirty water. Small objects like glass or food can block it. I once found a toothpick causing drainage problems. Cleaning the drain pump solves this issue quickly.
How to Fix Bosch Dishwasher Check Water Light Step-by-Step
- Check Water Supply: Bosch dishwashers need steady water pressure. Open the tap fully and check the flow. Users should run water for a minute to ensure an adequate supply.
- Inspect and straighten the inlet hose: Bosch recommends checking the hose for kinks. Straighten it gently and avoid sharp bends to prevent blockages.
- Clean inlet filter: Bosch includes a small inlet filter inside the hose connection. Remove it carefully and rinse it underwater to clear debris.
- Examine and clear the drain pump: Bosch dishwashers have a filter near the pump area. Remove the filter basket and clear any debris inside.
- Reset the Bosch dishwasher: Bosch allows users to reset the appliance easily. Turn it off, unplug it for 5 minutes, and restart it to clear errors.
