Roca LAIA confort avería 25 no funciona aveces se bloquea

Check boiler replacement parts at https://www.recamania.com/contactenos This Roca Laia Comfort diesel boiler locks up, turns on red, and stops. In this case, pressing the + and - buttons simultaneously for 10 seconds displays the number 25 on the screen. This code means there is poor contact in the external sensor or the electronic card. The solution in this case was to disconnect the yellow faston and reconnect it to improve performance. I did not replace the electronic card. In other cases, it also indicates that the building's external temperature sensor is broken. TRY THE TROUBLESHOOTING ENGINE https://miamigoarreglacalderas.com/re...
