I'd love to give it a go and see if I can get rid of this whistling. A few months back, I tried resticting the air flow in myself same as above by creating holes in a plastic cup and placing it over the intake. Works for a short period of time, but is not fool proof.

The first one lasted two years and Bosch replaced it no charge. The second one lasted four years after that and the controller went out. After a few back and forth's Bosch is going to replace it too. Can't say enough about how well they've treated me. I love my tankless water heater. I have the electric version, an AE125. The first one lasted two years and Bosch replaced it no charge.

My recommendation is to start a black list and don't buy these products anymore. i have a bosch tankless and can appreciate all of the comments. i can deal with the loud bass noise at startup, which is my only problem. i will not invest any more money in this heater. i am disappointed with the bosch customer service when i asked to speak to a tech about this issue. i will not buy all the fancy equipment to test this or hire someone to do so. i live in an older neighborhood and now understand that it must be lower gas pressure. i do have a 1″ gas line from meter to heater and a water softener installed before the unit. this technology just isn’t there yet.

Our Bosch tankless heater is a worthless appliance that frustrates us on a daily basis. Between the hot, cold, hot, scalding, cold and the shut-offs, we easily waste 20-30 minutes a day dealing with it, especially when trying to do something basic - like wash dishes or hands. Major pain. I would NEVER recommend this to anyone or purchase one again. Biggest nightmare ever. We are thinking of switching back to a tank. Just have to add my horror story to the bunch.

Bosch 250SX. Dripping water all over the floor, I'm waiting 2 hours on "hold", I finally got Bosch service to answer the phone. At that point, I got Scott on the line who spent the next 30 minutes on a mission to figure out how to cancel my warranty. He wanted to know if I had a "momometer" of something like that, what altitude I was at, if I had a water softener, how long my exhaust pipe was... (he wanted me to get up in the ceiling and measure it)... Finally he figured out a was to exclaim that the water heater warranty was VOID because the exchanger had compromised the gave jet by dripping into it and that possible moisture in the 21 foot exhaust pipe had caused the heat exhanger to fail prematurely and that it must be my fault. Now I have a boat anchor... I installed an electric hot water heater yesterday. If it fails.. Throw it away and save yourself a lot of aggravation! Don't call Bosch... They just want you to go away. Beware!!!!!!! Don't buy Bosch anything!! 3 years into a 10 year warranty I’ve just had a catastrophic failure of the heat exchanger.

The water flow is fine as I drilled a bigger hole into the shower head and have removed all the water restrictors from the taps. We have removed the cover to allow more airflow. I feel it ia a gas delivery problem. The gas lines in the area are 14 years old so small and low pressure is not an issue. Other people I have talked to have not had a problem wiht there heaters and love it. We hate it, cold showers are not fun. We have the spark operated by batteries. I have just contacted Bosch about changing it to ac. Make sure you don't have batteries when getting one!! Any suggestions on the problem, we want to get rid of it and get a tank again. Our gas bill increased when this one was installed!! We have a Bosch tankless heater and it quits producing hot water.

Then I have to go into the basement and reset it. I have never had the whistling but it does cycle repeatedly (flame goes out and tries to restart a few times)and make a noise when it is cycling. Sometimes after three tries or so to restart it will get an EC code. I have a long gas run so I ran 1-1/2 black all the way to just before the unit where it has to switch to 3/4. I also installed the second condensate drain as the service bulletin suggests but see no water coming from either one. I have removed the igniter a couple of times and found it had a slight reddish residue on it which cleand off with steel wool. I also found bugs on the top of the heat exchanger that flew into the vent so I cleaned out the bugs and put aluminum window screen over the vent cap. My problem seems to occur mostly in hot humid weather. I believe it is related to low flow rates since it mostly happens when you use the dishwasher or kitchen sink and occasionally the shower. I have it set to 120 degrees which is fine for showers but marginal for the dishwasher. We had a run of cool weather recently (first week of Sept) and it went for a whole week without requiring a single reset from the EC code. Then it went back to needing its daily reset. Maybe the incoming water temp is the issue, I'll have to start measuring it and see if it correlates. My wife and I are sick of the problem which has been going on for six months and about ready to yank it off the wall. Any suggestions would be appreciated.
