This is a "point of service" tankless water heater that was manufactured by BOSCH. BOSCH is now Bosch-Climate.us. Technical support is available at 866-330-2729. P.S. check this site: http://tanklesswaterheaterz.com/bosch-ae-9-5-powerstar-1-5-gpm-point-of-use-indoor-tankless-electric-water-heater-reviews/

Testimonial: "Uncle Bob was very help - provided the connection I needed to get the installation and use manuel. In addition, he forwarded a review that tipped me to be aware of a potential. Problem. I will install an electric cutoff for this cabin installation and the unit will have no power to it when not in use. FixYa is a gret site!"

SOURCE: i have a 250SX aquastar bosch tankless hot water

The 250 MUST have the condensate line connected. EC comes from gas supply problems and CO2 levels not being adjusted. LP units require 3/4" smooth gas pipe or 1" corrugated pipe minimum size. The LP regulator needs to be turned up to about 13 inches of water column and with all the gas appliances on, measure no less than 11 inches of water column. The CO2 levels must be measured by a qualified gas technician with a calibrated (with in 6 months) CO2 analyzer.

AE 125 Just Stopped Working Altogether,,,Still Has Power But No Light Or Hot Water?

Turn circuit breakers fully off and then back on.
Use nose to smell for burning inside main panel.
Make sure you are getting 240Volt and not just 120V from one leg of the breaker.
Do stress test on breaker panel.
http://waterheatertimer.org/Troubleshoot-household-electricity.html#stress

Least expensive solution: Replace tankless computer for $285 buying tank-type electric water heater from local box store.

If tankless computer is new, then call installer.
If you installed it yourself, call professional installer.

I've got the Bosch AE 9.5 tankless water heater.

1) Cheapest and most reliable solution: Install tank-type electric water heater from local box store for $250. Get store coupons, offer 10% off store price. Repairs are made same day with generic off-the-shelf parts.

http://waterheatertimer.org/How-to-solder-pipes.html

3) Remove areators and low flow shower heads, Maintain unit as shown in product manual: Delime tankless unit yearly, Clean water filter monthly.

4) Call city and report low pressure and report issue as fire hazard, move to different apartment. Call apartment complex and ask why they didn't read flow requirements for tankless before installing tankless.

5) Call Bosch 866-330-2729 and complain that nobody read the flow requirement or tested local water flow before installing tankless.

Bosch AE-9.5 keeps tripping the reset

All resets and breakers trip with high heat.
Do you mean the tankless unit is tripping the 40 amp circuit breaker?
Or the thermal cut-out, located on unit, is tripping?

Is this a new installation?
Or was the tankless working before and stop working?

Copy following link to check wiring.
AE 9.5 requires 40 amp breaker and 6 gauge wire.
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html

If the unit is tripping the thermal cut, -out, then product manual says to call Bosch or service technician.
Call Bosch 866-330-2729
http://waterheatertimer.org/pdf/Bosch-Powerstar-AE3.4-7.2-9.5.pdf
Thermal cut-out can trip if water flow is too low.
Try changing power selector screw from Hi to Lo so only 1 element is ON. See diagram page 6 of manual.
Adjust the 'outlet service valve:' The manual recommends that a ball valve be installed between hot outlet and faucet. Adjust the valve so more water flows to faucet.
Remove aerator, clean aerator, don't use low flow restrictions or low flow shower heads, replace leaky faucet cartridge on single-handle faucet.

I have a Power Star electric hot water heater, model AE 125, serial # 39-203967, model 45-55130. purchased 5 years ago at Home Depot for $850.00. I love the heater when it works. This is the second time I...

Bosch has 10-year limited warranty.
Probably the seller honors warranty first 90 days and Bosch afterward.

I think warranty is similar to car warranty where parts are covered, and they pay for parts to patch up the blown transmission but not give you a new car. But I hear of cases where the company just send a whole new Tankless unit and you install it yourself.

Contact Home Depot and present them with receipt.
Contact Bosch with the same information given in Fixya question.
