Risk level
Low
Usually safe to check without specialist tools.

Quick answer
INSERT WATER TANK (or INSERT TANK) means the water tank is missing or not seated properly: slide the tank in straight and push it as far as it will go. On the Magnifica S without a screen, the water tank light stays on steadily.
Safety first
Stop and check this first
- Rinse the water tank thoroughly with running water after washing it with mild washing-up liquid, before filling it with fresh water and putting it back.
- When INSERT WATER TANK appears during descaling, fill the tank right up to the MAX mark so the appliance does not have to request a third rinse cycle.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Slide the tank in straight and push as far as it will go
- Who:
- you, with no tools.
- How:
- pull the water tank out, check its lid is closed properly, and slide it back into the machine pressing firmly as far as it will go until it clicks into place.
- Result that matters:
- INSERT WATER TANK / INSERT TANK disappearing (or the steady tank light going out on the Magnifica S).
- If the alert clears and the home screen returns:
- the tank simply needed pushing all the way in.
- If the prompt stays on screen or you are mid-programme:
- move to the next check.
- Evidence to keep:
- photo showing the water tank sitting flush with the front of the machine.

Complete the guided step if fitting a filter or descaling
- Who:
- you.
- How:
- if the message appeared at step 9 of filter installation or step 15 of the descaling rinse, fill the rinsed tank to the MAX mark with fresh water, close the lid, push the tank back in, and follow the next screen prompt (place container and press OK).
- Result that matters:
- the guided procedure advancing to filter activation or the second descaling rinse.
- If the screen moves on to the container prompt and delivers water:
- it was a normal guided step.
- If it does not advance even with the tank full and pushed home:
- check how the filter sits inside the tank.
- Evidence to keep:
- note of the menu procedure and step where the message appeared.

Check the water softener filter housing and clean the tank
- Who:
- you, with a damp cloth and a little mild washing-up liquid.
- How:
- remove the tank, make sure any water softener filter (D7) is pressed as far as it will go into its housing (fig. 36), and clean the tank (as De'Longhi advises monthly) with a damp cloth and mild washing-up liquid, rinsing thoroughly before refilling and reinserting.
- Result that matters:
- ruling out a proud filter or dirt stopping the tank from reaching the end of its travel.
- If after reseating the filter and tank the prompt clears:
- the filter or lid was holding the tank back.
- If the message persists with a clean, fully seated tank:
- reach out to De'Longhi Customer Services about the water tank alert.
- Evidence to keep:
- photo of the filter housing inside the tank and of the seated tank.

What it means
According to the official De'Longhi Dinamica Plus support page for INSERT WATER TANK and the Dinamica Plus ECAM370.95 instruction manual, INSERT WATER TANK indicates that the water tank (A17) is missing or not correctly in place. On the ECAM 22.360 the wording is INSERT TANK, while on the Magnifica S ECAM11.1XX/22.1XX with indicator lights the water tank icon stays on steadily (flashing means low water). It also appears as a guided step when fitting the water filter or rinsing after descaling. Other De'Longhi models may differ, and the prompt alone never proves a part has failed.
