Smeg's built-in machines take water from a front tank. The display asks for a refill when the level is low, and also when the tank has been replaced without being pushed until it clicks. Smeg coffee machine display What to do when FILL WATER TANK WITH FRESH WATER shows on the coffee machine ### Kind of code Water and tank The machine asked for water and did not get what it expected: the tank is empty, sits off its seat or has a float the sensor cannot see, air is trapped in the line, or the flowmeter counted too little water passing in the time allowed. On a plumbed unit the same message can mean a closed shutoff, a kinked supply hose or a clogged inlet valve. Reseating a full tank and running a rinse clears the simple cases; a pump that hums with nothing moving is a visit. ### Usually leads to Coffee machine pump repair Testing and replacing the pump that drives water through the coffee, with the flowmeter that counts each cup and the valves beside it. ### Shows up as What a Coffee Machine Error Code or Warning Symbol Means A coffee machine error code may show as a short string of letters and numbers, a flashing symbol for water, grounds or the brew unit, a short sentence on a text display, or a machine that stops with one light blinking. ### Make Smeg A Smeg espresso machine is repaired at the owner's kitchen counter after a single test shot shows where the trouble begins. ### Source Smeg automatic built-in coffee machine instruction manual (linked from the US CMSU4303X, CMSU4104S and CMSU2104G pages) Smeg US built-in automatic coffee machines CMSU4303X (Classic, listed as retiring), CMSU4104S and CMSU2104G (Linea).

Remove the tank, open its lid and fill with fresh cold water to the MAX line marked inside. If it comes back, it needs a visit. ### Why does my Smeg built-in coffee machine keep asking for water after I fill it? The tank most often has not clicked into its seat. Press it in firmly until you hear the latch. ### What water should go in a Smeg coffee machine? Smeg asks for cold, fresh tap water. Leave out sparkling or warm water. ### Is it normal for my Smeg to ask for water during descaling? Yes.
