What to do if poolstar POOLEX Sel-in 20 Swimming Pool Filter shows Error E5 (salt concentration is too low)?

If your poolstar Swimming Pool Filter displays error E5, test the salt concentration of the water. If it's too low, add salt until the concentration reaches 3 g/l. Ensure the chlorinator is switched off until the salt has fully dissolved.
