I have an instantaneous Bosch Hot water system (Tank less) Model 22e.
stopped working, electrician white wire was burnt and was disconnected from the flat whit plug.
The Electrician by passed the plug and joined the wire. the heater works however the control display unit inside the bathroom shows only 40 *C and does not go up further. it doesn't seem to be broken or malfunctioning, hence when I move the select button to Bath mode the up button moves from 40 to 48 *C without a problem, I need to know how to set the unit, your support is much appreciated. Thank you

Hi, My Bosh hi flow 21 is making a very loud noise when I turn on the hot water.
I have cleaned the filter and run the water through, but still continues to make very loud noise.
I have a Bosch 25E highflow and the temperature doesn’t work in one of the bathrooms, what do I do?
How do I turn on my Bosch 26 Water heater? Ive just purchased a house and the previous owners have not left instructions for turning it on
I am in a rental and the Bosch Highflow 16 has stopped working. There is gas and electricity to the unit. What can I do please?

We have had one of these systems for years. Just lately when you have a shower the hot water cuts in and out. The shower goes hot and then cold. When watching the unit the light actually goes off and then you can see the gas start. What should we do?
Hi. We have Model 25e - we recently re-did our kitchen and as part of that changed the kitchen tap. I understand that the heater switches on when the water flow is of a certain volume (pressure). The pressure on the new tap is lower than on the old one and sometimes the heater does not switch on. Is there a way to change the setting for the triggering pressure?
Hi,
My Bosch hws turns on, but the water stays cold. I’ve had this issue before and by turning hws off at power it usually works. I’ve checked and in fact changed to a full gas bottle, (gas stove working fine this whole time.) checked power point that there is power to it (hair dryer works fine).
You can hear the how the system goes on... and water run through, but I don’t and cannot hear the pilot light start up like other times. System is only about 5 years old and serviced regularly.
Can you help me please?

Why does my Bosch Highflow 21e turn off when you put the cold water on
For some reason this morning, my wife turned the cold tap on in the kitchen and the fan ran in the heater unit. Can that be a pressure thing.?

Hello
I have a Bosch Highflow 17e.
Recently I have noticed that the red light on the remote controller thermostat unit is turning on and off while I am using the hot water (e.g. having a shower and the red light remains mostly on, moreso flashes of the red light going off).
I have also noticed temperature fluctuations more often duirng showers.
Because the weather has been hot in Adelaide I have recently reduced the temperate setting on the remote controller thermostat from about 41 to 37.
This morning, however, the red light was disappearing more often. It eventually came back on.
Do you have any suggestions?
Kind regards
Tony
We have a bose 21e and a main controller. Lately the water is too hot even when the controller is set to its lowest temperature
Hi Danny, you'll need to check if your gas and water supply valves are fully open. Additionally, if your water supply temperature is high, it's possible for the water temperature to be higher than wha...
Read moret is set on the controller.

I’ve never had gas hot water before and I knew it had its problems, as my daughter has been on gas hot water for years. This is ridiculous, we get hot water but trying to adjust it is unreal. You get it right and then it totally cuts out and no hot water at all. Turn off the water and start all over again as there is no hope of trying to remix it most of the time. The amount of water that’s going down the drain is unreal. Sorely disappointed. Before I contact the real estate I’d like to know can this problem be fixed or am I stuck with this reoccurring problem.
We have exactly the same problem. Reading the other reviews it appears this is a common problem. Also reading the reviews on here, don’t expect an answer but instead to be told to ring their customer ...
Read moreservice number where they will then recommend a service agent with gas plumbers having a general minimum charge of $300. Either way your stuffed!Thanks, I’ll put it to the real estate and ask if the landlord is willing to have it looked at.

Yesterday we had intermittent power outages until we had a full blackout for around 3-4 hours. Since then my Bosch26E unit will not provide hot water. The Burner indicator on the bathroom controllers is not lit and the gas unit itself does not ignite when the hot water is turned on. The controllers then default to 11 deg. Any ideas on how to do a full system reset ? Cheers John.
