Troubleshooting Guide

In our latest article we look at some common submersible pump problems and how you can overcome them.

Does your pump not start?

There may be a number of reasons why your pump doesn’t start. Having checked the power supply, the next thing to check would be that the fuses haven’t blown and need replacing. Is the cable damaged? If so either remove the damaged section or replace it, likewise check that the stator winding hasn’t burnt out and needs replacing. It’s also worth examining the impeller to make sure they’re not blocked or jammed; if so, simply clean the wet end out.

Pump starts but then stops?

 

This may occur if the impeller is blocked or the strainer clogged; both can be overcome by cleaning of the parts. It is also worth examining the pipe to ensure sure that isn’t blocked. Failing this, the voltage may be either too low or too high in which case contact your power company. Another possible cause is that the impeller rotation is wrong. Finally, if the pump is running dry or the water is too warm (above 60 degrees C), turn off the power.

 

It may also be worth looking at the overall picture – is the pump still suitable for the application? Feel free to contact us if you are unsure.

Is the pump giving too little output?

 

There are a number of reasons why this may occur. Firstly the impeller rotation may be wrong. Secondly, check the wear parts and replace them if worn out. Also examine the outlet and replace if leaking or cracked. Another reason why the pump may be giving too little output is if the pressure head is too high; where this is the case, use the pump in tandem. If the discharge hose has torn then replace with a new hose. Also check that the pump is drawing enough water.
