Most things with a change light are based off a timer (or maybe a counter) and nothing more.
There's no mini-lab or sensor in your fridge actually testing if the water filter is working.
And even ones that claim to measure how much volume is dispensed are just counting how long the water valve is open and assuming a flow rate.
That said, the filters do go bad, and sometimes even provide media for stuff to grow on, once the contents become chemically and physically inert. If you don't want to change the filter, get a "blank" to plug in. Don't just leave an old filter in.
- pier25 7y agoThanks for the idea of the "blank filter". I found out it's called a "bypass plug" and apparently it should have come with my fridge.
- hvidgaard 7y agoOur coffee machine at work has a filter. If we set the water hardness to the actual value of our water, it needs replacing quite often. So I've dialed it down and the filters last significantly longer. When we got it serviced last time I asked the technician to look if it needed descaling - it was squeaking clean inside the boiler, so I've dialed it down even more.
