SOURCE: Vaillant turbomax 28 constant hot water problem.

got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps

Q. FA - Gas leakage error, gas valve circuit not closing properly
A.

  1. Disconnect power supply cord and check wire connections on gas valve and the two connectors on the control board.
  2. Flow water out of a hot water tap above the minimum activation point of .8GPM. Measure voltage at the gas valve wire connector. The connector should measure 24VDC between the left pair of wires and 24VDC between the right pair of wires when the unit is operating. If voltage is not correct, contact Bosch Water Heating for further instruction.
  3. Gas valve may be defective, contact Bosch Water Heating for further instruction.
Q. EA - No flame ionization detected with water flow
A.
  1. Verify that all manual gas shut off valves are open.
  2. Verify gas type (See Fig. 2 in installation manual) corresponds with the type of gas supplied to the heater.
  3. Reset error code and open a water tap to cycle the heater in an effort to purge air from gas line (especially on new installations). Cycling hot water tap on and off multiple times may be necessary. If heater still faults with EA error code, have a licensed gas technician properly purge air out of the gas line leading to the water heater.
  4. Verify the three yellow wire connections to the set of electrodes (underside of the burner assembly) are secure.
  5. Verify gas pressure meets specifications outlined in chapter 3.8. See Bulletin TWH-G2-03.
  6. Verify venting meets specifications outlined in chapter 3.6 of the installation manual. Improper venting may cause premature failure of the flame sensor rod.
  7. Observe inside the viewing window of the heat exchanger when a hot water tap is opened. Sparking should be followed by a steady blue flame. If not, Call Bosch Water Heating with observations. Readings from above gas pressure test will be required.
Q. C1 - Fan rotation too low on startup
A.
  1. Disconnect power supply cord. Check wire connections on back side of fan and the two large wire connectors on the control unit. Removal of lower access panel on control unit is necessary to access connectors.
  2. Verify that supply voltage is 120VAC and is properly grounded.
  3. Verify that venting meets specifications outlined in chapter 3.6 of the installation manual. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure. Verify backdraft flapper inside flue gas collector is not stuck shut.
  4. Check gas pressure. See Bulletin TWH-G2-03. Low gas pressure may cause the fan to change its speed to meet desired temperature.
  5. Possible defective control unit. Call Bosch Water Heating for further instructions.

SOURCE: Grohe bath faucet adjustments

grohe is a faucet all by itself ,,, I would recomend to have you call there repair dept. and explain this to them, you said you put in the new cartridge and thats about all there is to it, when you put on the handle make sure it is not over tightened, sometimes it pulls on the cartridge and makes it come on by itself good luck

SOURCE: bath tub water doesn't stay hot

it is because the tub has a temp control valve in it so if you were to put more cold with the hot it will last longer but still won't be all the way hot,, now a days people are suing the manifacture because they are getting burned form the hot water so they put these saftey temp controls in place of the old style 2 or 3 handle faucets,, there fo no more real hot water nothing you can do outside of change to the othere type of faucet 2 or 3 handle tub shower diverter,, that why the water is hot in the sink but not the tub.....

Vokera aav leaking


Robert, i'm sorry to say but the AAV's are machined parts and the seal should not have been broken by removing the cap. The floats are set perfectly and you would have been easier replacing the whole vent. You could have isolated all the pipes under the boiler and just drained the boiler down by releasing any pressure by the pressure release valve. You may need to buy another AAV and start again.

Upsstair shower doesn't supply continuous hot water, downstair works great. Water pressure problem?


It could be a water pressure problem but most water supply companies put out enough pressure for a 2 story house (or even 4 stories) easily. Can you clarify what you mean by continuous? Does the water get cold, on and off (i.e. no hot water) or does it vary in temperature mildly?

Low pressure on recently serviced Vokera 14/48se.


Identify the cold feed to the boiler, then look for a tap/service valve which when turned lets water into the boiler via a fill loop to pressurise it. 1-1.5 bar is ok

Water is not hot enough and the temp is on 120 I have a notiz tankless hot water heater


check your gas pipe size. make sure you have enough gas running to the unit. also turn all your faucets on hot and turn off the cold water to the heater and see if you get any water out of the hots anywhere, that could mean that you have a cross connection.

I have a similar problem with this boiler. When CH on, boiler overpressurises, (check relief valve outlet) You will then lose water from the CH loop and will have to repressurise when the CH loop cools. The problem is most likely caused by a loss of air from the expansion tank, which will need re-charged. This is not a big job as it has a standard tyre type valve connection but needs an accurate pressure gauge. Probably best left for plumber.
