Frequently Asked Questions - AquaGo (detartrage) TRUMA

How do I start the decalcification process on my Truma AquaGo?

Turn off city water and allow the system to cool, open a hot water faucet to depressurize and drain, remove the filter using the yellow lever, insert 6 decalcification tablets, reinstall the filter, turn on city water, switch the AquaGo on, and then select Clean mode on the analog dial or CP plus controller.

How long does decalcification take?

The decalcification cycle lasts roughly 2 to 3 hours. There is no way to speed it up or cancel after the pump starts, except for a 30-second window on the analog dial immediately after selecting Clean mode.

Why is the water pink during the cleaning cycle?

Pink water is normal due to the decalcification tablets dissolving. It will clear when you flush the system with fresh water during the rinse phase.

How much water is needed for the rinse cycle?

You need to flush approximately 8 gallons of water through the hot water faucet to remove cleaning solution and debris from the system.

What does the red LED fault code 31 mean?

Fault code 31 is indicated by a red LED blinking in the sequence S,S,S,L,L,L,L,L (3 short, 5 long) and means Decalcification Complete. The unit is ready to be returned to normal operation.

How do I wake up the analog dial after cleaning?

Slowly turn the dial from Off to Comfort to Eco and back to Off, repeating as necessary, until you see a solid amber light. This indicates the dial is active.

What should I do if the AquaGo is stuck in clean mode?

Make sure the unit has power and the outside toggle switch is on, set the analog dial to Clean, wait for the circulation pump to cycle, then open a hot water faucet until the amber light stops flashing. Afterwards, turn off the toggle switch, reset the dial, and turn everything back on.

How do I reset the CP plus controller?

Select the wrench icon on the CP plus, choose Reset, press the center button, confirm with PR SET, and wait for INIT to complete. The screen will return to the digital clock.

Can I cancel the cleaning process once it has started?

For the analog dial, you have 30 seconds after turning to Clean mode to cancel. Once the circulation pump starts, the decalcification cycle cannot be cancelled and must finish.

Why is the circulation pump turning on and off during cleaning?

The pump cycles intermittently to circulate the descaler through the heat exchanger. This is normal, and the burner will not ignite during the cleaning process.

Truma AquaGo Decalcification Instructions

Please use city water for the cleaning process to ensure you have enough water to complete cleaning process. To start the decalcification process please follow these steps:

1. Turn off city water and allow the system to cool off.
2. Turn off Truma AquaGo at the toggle switch on the outside of the RV.
3. Go inside the RV and open hot water faucet to allow system to depressurize and water to drain. Wait until water stops flowing out of faucet and then close the faucet.
4. After system is depressurized, go back outside to the Truma AquaGo. Stand off to the side and slowly pull the yellow "Easy Drain Lever" down and remove the filter.
5. Open the decalcification tablet pack and insert all 6 tablets into the filter screen.
6. Place the filter loaded with the decalcification tablets back into the water heater, close the yellow lever, and snap in place.
7. Turn on city water.
8. On the outside of the RV, turn the AquaGo toggle switch to the "on" position.
9. Choose a faucet with the highest pressure and a removable screen/aerator for this process. Remove the screen so debris being flushed during the rinse cycle will not clog the faucet screen and the flow sensor can read the gallons per minute accurately.
10. Go inside and turn on a hot water faucet. Allow the air to be purged from the lines. The water coming out of the faucet may be pink in color, this is normal. Turn faucet off.

During the cleaning cycle, the circulation pump will turn on intermittently, this is normal. The decalcification process will take roughly 2 to 3 hours. There is no way to speed up this process or cancel after it has started.

From here, the decalcification process will depend on which control module your Truma AquaGo uses. Please refer to the instructions for your control module below.

Analog Dial

To the right is a picture of the analog dial with an amber backlight.

After depressurizing the water system, turn the analog dial to "Clean" mode. During the cleaning process, the amber light will blink slowly. When the analog dial is turned to "Clean" mode, you have 30 seconds to cancel the cleaning process. After 30 seconds the circulation pump will turn on and the decalcification process will begin, even if there are no decalcification tablets in the filter.

After the cleaning process is complete, the amber light will blink rapidly.

1. Once light blinks rapidly this means that the unit is ready to flush. You will use the hot water faucet with the highest pressure and a removable screen/aerator for this process. Turn the faucet on and flush approximately 8 gallons of water through the system. Once enough water has flushed through, the light will stop blinking rapidly and blink two times with a pause. There will be a blinking red LED light below the toggle switch on the outside of the AquaGo. Red LED light will blink 8 times in the sequence of S,S,S,L,L,L,L,L. This is fault code 31 "Decalcification Complete".

2. Turn the analog dial to "Off." On outside of the RV, turn the AquaGo toggle switch to the "off" position. Wait 1 minute.

3. Turn the AquaGo toggle switch to the "on" position and then go inside and turn the analog dial on.

4. Slowly turn the analog dial from "Off," to "Comfort," to "Eco," back to "Off" and then to "Eco" again. You may have to do this a few times to "wake the dial up." You will get a solid amber light when this is successful.

CP plus Controller

To the right is a picture of the CP plus controller. After depressurizing the system, follow the instructions below to initiate the AquaGo cleaning mode.

1. Turn dial until the wrench icon is selected and push the center button, turn dial to select AquaGo and push the center button, turn the dial until you see "Clean," and push the button to activate cleaning mode.
2. The screen will say "clean" while decalcification is in progress.
3. The screen will say "rinse" when the cleaning process is complete.
4. You will use the hot water faucet with the highest pressure and a removable screen/aerator for this process. Turn the faucet on and flush approximately 8 gallons of water through the system.
5. Once the rinse cycle has completed, an "E31" code will appear to indicate decalcification is complete. Turn off the water.
6. Push the center button twice to revert to the main screen and resume normal operation.
7. On outside of the RV, turn the AquaGo toggle switch to the "off" position. Wait 1 minute. Turn back on.

Resetting the CP plus

If there are multiple Truma appliances connected to the CP plus you will need to reset the CP plus to get the other device(s) to back online.

1. Turn dial until the wrench icon is selected and push the center button.
2. Turn the dial until "Reset" is selected and push the center button.
3. The screen will say "PR SET," push the center button again.
4. The screen will say "INIT," this means the system is initializing. When complete, the screen will return to a digital clock.

AquaGo stuck in clean mode

1. The Truma AquaGo must have power from the main panel.
2. The outside toggle switch on the AquaGo needs to be in the "On" position.
3. Turn the analog dial to "Clean" mode (this is the bottom position on the dial)
4. Wait until you hear the circulation pump cycle on and off. You may need to "wake the dial up" by turning it on and off a couple of times until you hear the circulation pump cycling.
5. Open a hot water faucet, let the water run until the amber light on the analog dial stops flashing. This could take 15 minutes or more. During this time, you will hear the circulation pump turning off and on intermittently. This is normal and the burner will not ignite.
6. Once the flush cycle is complete, the green LED above the toggle switch on the outside of the AquaGo, will go off. You will see a red LED light fault code below the toggle switch. This is fault code 31 (S,S,S,L,L,L,L,L) "Decalcification Complete".
7. Turn the toggle switch on the AquaGo to the "off" position.
8. Go inside and turn the analog dial to the "off" position and wait 30 seconds.
9. Turn the toggle switch on the AquaGo back on- solid green light should be present
10. Turn the analog dial to the "ECO" or "Comfort" mode. You may need to "wake the dial up" by slowly turning it on and off a couple times. The unit should work normally at this time.
