Hi experts, i have a question for grundfos water pumps. My friend is facing an issue with his tsunami pump. During the water rationing days few months ago, his water tank went dry and empty.

When water starts to re-fill the tank, the water pump will not automatically pump water. The user has to go up to the pump in the rooftop and manually press the reset button for it to work again.

Does CM3-5 PM1 comes with auto-reset function? or do i still have to manually reset it?
