Why does the whirlpool tub overheat?

Hot weather in the region where your whirlpool tub is located can be the reason why the water temperature rises. Switch your whirlpool tub to power-save mode, minimise the filtration time and open the cover so that the heat can escape. Never leave an uncovered whirlpool tub unattended for safety reasons. The indication „OHH“ on the control means that the thermometer has measured a whirlpool tub water temperature over 43.3°C.
