To troubleshoot Kohler toilets, you must first identify the specific problem. Common problems with Kohler toilets include poor rim wash, toilet running continuously and difficulties adjusting the amount of water in the tank. Other problems include failure to flush and porcelain cracks.
Always follow the manufacturer's guidelines on troubleshooting Kohler toilets since specific models require specific solutions. Poor rim wash in Kohler toilets is often as a result of rim hole blockage. To fix this, cut off the toilet's water supply, and flush any excess water in the tank. Using a paper clip, clean out any dirt blocking the rim holes. Plug the holes using paper towels and sprinkle lime cleaner on the rim inlet. After the deposits have dissolved, remove the paper towels and then clean the toilet properly before use.
A Kohler toilet may run continuously if the fill valve is problematic. To fix this, limit the amount of water coming into the toilet, then remove the toilet tank cover. Locate the valve cap in the tank and remove it. Check for a black seal in the valve cap and clean it thoroughly, or replace it if it is damaged. Reassemble the toilet, and restore the water supply.
To adjust the amount of water in the toilet tank, check the water level marker on the toilet tank. Move the fill valve to the recommended level as instructed by the manufacturer.
