What to do if my Coleman Water Pump displays 'Er' or the app says 'Filter pump detects no water flow'?

If your Coleman Water Pump displays "Er" or the app indicates no water flow, it could be due to several reasons. First, ensure the pool's inlet and outlet are fully submerged. Next, purge any air from the circulation system. Also, check that the control valve is fully open. Clear any blockages from the hoses or debris screen. If the filter cartridge is dirty, rinse it or replace it with a new one. If the timing interface is open and the filter pump is off, visit www.bestwaycorp.com for assistance.
