Water pump

[Keith777]

After changing my leisure battery (not going to tell you why I had to change the battery !)as soon as I connected the new new one the water pump started depositing water out of the overflow pipe, now every time I switch the pump on the same thing happens. Can any one help oh knowledgable ones !
Mh is a rimor katomorano .
The pump is an aqua 8.

Water heater frost protect dump valve open.

It should be somewhere near the boiler in the blue pipe....maybe a yellow lever
lift or push the lever.

When you disconnect the electric it automatically dumps the hot water.
