Overload protection
The built-in thermal overload trip prevents the pump from being overheated.
The pump must cool down. When cool, the pump will start automatically again.
Check the following operating conditions:
- Is there a sufficient water supply?
- Has the filter become clogged?
- Has dirt entered the pump housing (Follow the cleaning instructions below)?
- Have hoses or jets become clogged?

As soon as you have solved the problems, you can start the pump again.
