Сохранение пламени на горелке колонки после закрытия крана горячей воды. Keep the flame on the GWH.

Warning: Operating a gas water heater with this malfunction is dangerous!!! This describes a rare situation, little known even to specialists in domestic gas equipment. What I forgot to mention in the video: if the water unit pressure switch is not working properly, the microswitch platform tab may slowly return from its "frozen" position to the microswitch after closing the hot water tap. This situation may not be permanent, but if you notice it recurring twice, you should contact a specialist and have the problem corrected.
