How Micro Switch Work On Saniflo Pumpsunionwellswitch
Saniflo pumps are a common feature in many homes that allow you to remove waste when flushing from below the drainage line. However, the demand for saniflo systems to be robust and quiet yet smaller for fitment presents a problem. Saniflo pumps are more likely to block, fail or break. To help you identify the potential issue with your Saniflo, here are some tips for using Saniflo. It helpfully listed the most common Saniflo problems and how to deal with them.
1. My Saniflo keeps running and will not switch off
One of the most common issues with Saniflo pumps is that they occasionally fail to switch off. This is where the pump is flushed, even when the macerator is clear. Unfortunately, diagnosing the source of this problem is not easy. It could be caused by one issue or a mixture of issues. These include A blockage in the Saniflo macerator or pump, A blockage in the Saniflo waste pipe leading outside, A pump’s rubber membrane being damaged A microswitch being faulty.
A blockage in the macerator. First, turn off the power to the pump at the main supply. Then, check if there is a blockage in the pump’s macerator. If so, clear it. It could be that toilet paper, or floss is stuck under the blade. To do this, use a pair of thin-nosed pliers and turn the blade counter-clockwise, removing the waste as you turn.
2. A blockage in the pump
It could also be a blockage in the actual Saniflo pump. This could be caused by cotton buds or other foreign objects blocking the impellers. Most Saniflo pumps are located underneath the motor, sitting in the water tank. To access this, lift the motor out of the Saniflo and turn the unit upside down. You will now be able to see the pump impellers. Using the pliers, clear the blockage and slot the motor back into place. Alternatively, it could be an issue in the water tank causing the microswitch to misfire. You will need to clear the tank by hand and restart the pump.
3. A blockage in the Saniflo waste outlet pipe
If the return valve is blocked, you will find that the pump is flushing waste out of the Saniflo, but the waste returns as it hits a blockage. To clear this, take your thin-nosed pliers, remove the lid of the Saniflo and clear any blockage from inside the return valve. If the return valve is faulty, it will need to be replaced.
4. The microswitch is misfiring
A common issue with Saniflo products is a misfiring microswitch. This is where waste gets lodged between the switch and the tank floor, causing the switch to thinking the tank is full and needs flushing. You will need to clear the tank by hand and restart the pump.
5. The rubber membrane is damaged
Another issue with microswitches is that the rubber membrane can get damaged. This is the thin piece of rubber that water presses against to switch on the pump. If the membrane gets damaged or loses its seal, waste can enter the switch and cause a fault. If the pump is still within the year warranty, you will be able to get a replacement system. If not, you will need to call a Saniflo-certified engineer to fix the switch.
6. My Saniflo keeps randomly starting
If the pump keeps randomly firing at different times of the day and night, you likely have a problem with the micro switch. This could be caused by either a fault with the rubber membrane that activates the switch, or it could be that waste is lodged between the switch and the floor.
A misfiring microswitch can occasionally happen when waste gets lodged between the switch and the tank floor. This causes the switch to think the tank is complete and needs flushing. To fix this issue, clear the tank by hand, remove any excess waste near the microswitch and restart the pump. The rubber membrane is damaged. The rubber membrane is the thin piece of rubber that water presses against to switch on the pump. If the membrane gets damaged or loses its seal, waste can enter the switch and cause a fault. You will need to replace the rubber membrane and switch.
