There might be a buildup of hair, grime or limescale. Turn it upside down and give it a careful shake to see if you can free up anything that is stuck inside.

The inlet valve that sucks the water from the hot tub to the filter and heater might be blocked. Water will not cycle correctly around the filter if uneven.You must move your hot tub correct the ground it is sitting on.Check your filter/heater is sitting straight.If your filter is sitting on uneven ground then this must be rectified because water will not get released correctly and the alarm will sound and the filter and heater will stop.

The pump housing displays an E02 warning which will cut off the pump and heating system, or the housing just cuts out altogether. This is more relevant for Lay-Z-Spa hots tubs although other brands do have this fault function.
