Hello and thanks for having this option to be able to find a solution to the technical problems of some devices. The water heater in question is 7 liters ionized. The problem is possible water pressure. I explain the device is installed in the kitchen with gas discharge through the shaft (it is a building) at 3.5 Mts. is to the dishwasher and behind the wall where the heater is installed more or less 50 cm. since the shaft is the shower. the funny thing is that when opening the dishwasher key does not turn on and I must play with the water pressure through the stopcock of the heater, however when opening the shower there are no problems. Of course, with the dishwasher the smallest variation made with the water and gas controls of the water heater, it goes out. The model is "Calefont Liquefied Gas 7 liters ATDV 7 ION Albin Trotter" and I have always had this problem, the water heater is approximately 6 years old and has been kept clean (outside) always avoiding dust accumulation on the sensors that are in sight [img] https://adjuntos.yoreparo.com/imagen_post/0004/34/5fdec1288eb8e8e08e8eb1e08eb08e02e07 img]
