What to do if the Optimas SV 200 E pump rotates, but doesn’t suck in?

If the Optimas Lifting Systems pump rotates but doesn't suck in, it could be due to a few reasons. First, check if the external air valve is open and close it. Then, inspect the dust-proof grid and clean it if it's jammed. Also, ensure the rubber sponge is correctly mounted; if it's damaged, replace it.
