💧 What Are Truma Decalcification Tablets?
Truma Decalcification Tablets (part no. 77300-01) are specialized cleaning tablets made to remove and prevent limescale buildup inside the Truma AquaGo water heater.
Each 6-tablet pack is formulated to dissolve mineral deposits that naturally form when using hard water, helping maintain:

-
🔒 Extended system life
They’re quick-dissolving, non-corrosive, and completely safe for use with all Truma AquaGo Comfort and Comfort Plus models.

🧽 Why Decalcification Matters
Hard water contains calcium and magnesium that accumulate inside your heater’s heat exchanger over time.
Without regular decalcification, this buildup:
-
Reduces water pressure
-
Increases energy consumption
-
Causes uneven heating
-
Can permanently damage components
Using Truma’s official tablets ensures safe descaling without risking chemical damage or voiding your warranty.
🔧 How to Use Truma Decalcification Tablets
For AquaGo Easy Drain Lever Models
-
Turn off power and allow the unit to cool.
-
Open the Easy Drain Lever and drain the system completely.
-
Insert all 6 tablets (full blister pack) into the water inlet filter.
-
Re-insert the filter and power on the unit.
-
Let the tablets dissolve (≈ 10 minutes); water may turn slightly red.
-
Run the system’s full cleaning cycle (about 3 hours), then rinse thoroughly.
For AquaGo Units with CP Plus Control Panel
-
Select “Clean” mode on the display.
-
The screen shows “clean” during the process, then switches to “rinse.”
-
Flush ≈ 8 gallons of fresh water.
