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.?

Electronic Highflow 26e

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.

Electronic Highflow 26e

Hi I have a bosch 26e highflow. Its been in about 5 years. its installed in a recessed wall box. Over the last year it periodically does not heat the water. I thought it might be a air lock in the gas as the unit switches itself off. I run the stove top to check the gas which seems OK and then I have been turning the unit off at the power supply and it seems to reset it and it works fine for 4 or 5 weeks. Then the problem starts again.
It is now turning itself off when I turn the shower on. it runs OK with the basin going, but as soon as it needs to increase flow it shuts down.
It also seems like when the basin is running it only has heat coming out of 1 side of the flue. Is this unit 2 stage? It has never been serviced but assume the only serviceable piece is the water filter.
Do you know of a common fault with these symptoms? and the fix?

I have seen lots of posts with the same issue. It is at a stage where I don't want to spend money trying to fix it when a new unit is a better alternative. I also noticed when looking for a bosch replacement unit is that you have changed your models to optiflow can you still but the Highflow? as when I checked the Gas and water connections they are different on the optiflow. Will the Optiflow fit into the Highflow recessed wall box.
If I have to change recessed boxes and plumbing I'll be putting in a Rinnai, 5 years is not a reasonable life span on a HW unit these days. Your assistance would be appreciated.

Electronic Highflow 26e

We lost power generally, and when it finally came on, the Bosch Optiflow has been on constantly boiling water even when not one is using hot water. What could be the reason? How do I turn it off?

1 answer
Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Phil, if your unit is running continuously with no hot tap on, there could possibly be a leak in your hot water line. We recommend that you shut off the water isolation valve to the unit and phone a service agent. If you need assistance in getting in touch with a registered service agent, please contact us at 1300 30 70 37 any time between 7:30AM to 6PM (AEST) on a weekday.

Electronic Highflow 26e

Our Bosch 26e unit is installed in the wall directly behind the main bedroom bed. This wouldn't be an issue except the unit beeps 7-8 times every time the hot water is turned on after being off for a few minutes. Very frustrating in the middle of the night! Is this beeping normal and is there any way to turn it off?

1 answer
Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Declan, we're sorry to hear about your grievances with your unit. Unfortunately, there are no user adjustments available on this unit.

The noise you are hearing is the water valve adjusting to the correct position for optimum start up performance. This is normal and unfortunately cannot be turned off.

My Bosch high flow 26e water heater is leaking, I called a emergency plumber but he wouldn’t touch it as it’s the heat exchanger that’s sprung a leak, which he said has a ten year warranty. Can you confirm this please.

Hi Carol, we are so sorry for the delayed response - due to ieatwords updating its platform, we have missed questions that were asked a while back ago.
