SOURCE: Hot Water Heater in 1991 Pace Arrow RV is not working

If you look on the outside of the RV, you will find the vent for the water heater behind and access door. There usually is a drain plug and valve located as well. Generally they will be tucked away under the kitchen sink area with internal access as well. You will need to find where the valve that shuts the water off to the unit is and turn it on. Most times the water heater is either electric or propane. But sometimes they are only propane. Once your find the access door, you will know where the water heater is. You can also contact Fleetwood who makes the Pace Arrow to see if they have any information on your unit. Usually your unit info or trim number will be located on a little plaque right by the entrance to the RV. You will need this when you contact them. Hope this helps.

SOURCE: takes too long for hot water.

You need a recirculating line. You will have to hire a plumber to run a water line from the farthest fixture or to the fixture you are concerned about on the hot side and return it back to the water heater. this will cause hot water to constantly run throught the hot water line (via the recirculating line) and when you want to draw water from the fixture, you will already have hot water right at the line.
I know this works with standard tank water heaters, but it is a lil trickier with rinnai units(but very possible) if your plumber pleads the 5th and tries to sell you another unit call the Rinnai manufacturerand ask them how.

SOURCE: Exterior mounted Rinnai tankless water heater not

What is the outside temperature? If it it is below freezing, you might have a frozen pipe. Using a plumber torch heat up the pipe, if it works, replace the insulation using a heavier layer.

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.

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.

My Boch 24ES Highflow Hotwater is showing Code 14 and only runs for i minute then shuts off


Code 14.
What water heater do you have?
Question posted under tankless Bosch, but these error codes start with a letter.
Rheem/Richmond etc Tankless has error code 14
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Paloma-Tankless-Error-Codes.pdf
Call tankless service technician.
Ask technician how much it costs to have recommended yearly service.

Or install whole new tank-type gas water heater yourself for $350 from local box store, and avoid the entire headache, then sell tankless online for parts.

The eco 180 dv tankless water heater will not turn on unless you run the tub/shower and lavatory at the same time. Running only one fixture at the same time will not kick on the water heater.


You have tankless water heater, and no error code.
Burner does not activate with one faucet, but activates with 3 faucets.
Best suspect is crossover:
http://waterheatertimer.org/Crossover.html
http://waterheatertimer.org/pdf/No-Error-Code.pdf
Problem can be a combination of causes including Tankless part failure: sensors are not working, PC board is bad, wires are loose. Call service technician to catch up on yearly maintenance and troubleshoot problem. Tankless water heaters require yearly maintenance.

The reset thermal cut-off keeps tripping


I am a free answerer, and I specialize in giving you resources for free
The paid answerers may have a person who knows your product and the problems associated with your model.
I believe they offer a refund if the 'fix' doesn't work.
The manual might also have troubleshooting.

Each day I see 20-25 unanswered questions about tankless water heaters.
And the day before, there were same number of unanswered questions about tankless products.
The number of questions shows the complexity of the machines, the brand-specific-ness of the problems, and the inability of the manufactures to take care of their customers.
If I understand correctly, the manufacturer will refer you to the installer.
There are not many ways a do-it-yourself-er can fix a tankless.
And a repair generally takes somebody trained by the manufacturer.
