    Other problems Problem or error Possible cause Solution/points to check A. No hot water when tap is Check whether the boiler is switched on Boiler is not running turned on check whether a fuse has blown; check whether the gas tap is properly open. Water pressure is too low (less than 1 Check mains cold water pressure bar)
  • Page 131 230 V Topping up the central heating system The Remeha Avanta Plus runs best with a water pressure of between 1.5 and 2 bar (see the water-pressure meter at the bottom of the boiler). If the water pressure falls below 1 bar, the system has to be topped up with water.
  • Page 132 • When topping up, use a filling loop, a cloth and a bleed key. LTALW7H000229a LT.AL.W7H.000.229 Top the Avanta Plus up as follows: • Attach the filling loop between mains cold water inlet and CH return.
