If your toilet macerator stopped working, don’t panic! There are a few things you can do to troubleshoot the issue and get it up and running again. First, check to make sure that there is power going to the unit.

If the unit is plugged in but not receiving power, try resetting the circuit breaker or replacing the fuse. If there is power going to the unit, check to see if the float switch is activated. The float switch turns on the macerator when water is present in the tank and shuts it off when the water level drops.

If the float switch is not activated, it may because it’s stuck in the “off” position or there isn’t enough water in the tank to trigger it. If you’ve check for power and verifie that the float switch is activate but your toilet macerator still isn’t working, then it’s likely that something is jammed in the impeller blades. The impeller blades chop up waste so that it can flush down through small pipes.

If they’re jammed, they won’t be able to do their job properly and will need to clean out. You can do this by removing the macerator unit from its mounting bracket and disassembling it according to your manufacturer’s instructions. Once you have access to the impeller blades, clear away any debris that may be blocking them and reassemble everything before putting everything back in place.

With a little troubleshooting, you should be able to get your toilet macerator up and running again in no time!
