Why is my Coleman SaluSpa 90427E pump not heating properly?

Your Coleman Hot Tub pump may not be heating properly for several reasons. Ensure the temperature isn't set too low; if it is, set it to a higher temperature. Check if the filter cartridge is dirty and clean or replace it. Also, confirm the spa is covered. If the thermal cut-out has tripped, unplug the pump and let it cool until the water temperature reaches 35°C (95°F) or lower before restarting. If the heating element has failed or the fuse has cutout, contact your local Bestway After Sales service point to get instructions.
