Bosch combi 151 ZWB 42-3A. DHW heats up in tank when all faucets off. Heats to 135 and flame light goes on. When Hot water is turned on at faucets temp gauge goes down slowly to 60 and flame light never comes on untill all faucets closed and tank fills back up. Just had unit serviced last month and the DHW temp sensor was replaced due to an error code. But never lost hot water. No error codes now just no hot water.
