That is thirty seconds of the job. The reason it deserves a page is that a filter past its life produces **three separate complaints at once**, and they get reported as three different failures: - **ice arriving slowly**, or the bin never filling;- **cubes coming out small, hollow or partly formed**;- **water or ice tasting of something** it should not. People book a service call for each of those in turn. A fair share of them are one cartridge that is six months past due. ::: ## Why flow goes before taste A filter cartridge works by pushing water through a carbon block. As it loads with what it has taken out, **the flow drops first**. Taste is the last thing to change, not the first. That is exactly backwards from how people judge it — "the water tastes fine, so the filter must be fine" — and it is why the interval exists at all. Six months, or when the machine asks, whichever comes first. ## Changing it - **Find it.** On most machines it is inside the compartment, in a housing on a wall or in the ceiling of the fresh-food section; on some it is behind the plinth at the bottom. If you cannot see one, look for a small door or a recessed handle rather than a cartridge.- **Turn or pull.** Most are a quarter turn to release, some pull straight out. Have a cloth ready — a small amount of water comes with it.- **Fit the new one** and make sure it seats fully home. A cartridge that is nearly in lets water bypass it, which is the least useful outcome available.- **Flush it.** Run **a couple of gallons** through the dispenser and throw it away. This clears carbon dust and, more importantly, air.- **Reset the indicator.** Usually press and hold the filter button for a few seconds. A quick press does nothing on most models. ## What the first two batches of ice will look like Small. Hollow. Sometimes barely formed at all. ::: That is **air in the line**, not a failure. The cartridge and the plumbing around it were full of air, and it reaches the ice maker before the water does. Discard the first two batches, let the machine run a day, and judge it after that. The other cause of small cubes after a change is a cartridge **not fully seated**, so water is bypassing it and the pressure at the fill valve is wrong. Worth pushing it home again before assuming anything else. ## Generic cartridges, honestly Plenty of them fit and some are perfectly good. What varies between them is **flow rate**, and that is the thing that matters for ice. A cartridge that filters well but restricts flow more than the original produces exactly the small-cube and slow-ice complaints you were trying to solve. If a machine began making poor ice shortly after a cheap filter went in, that is the first thing to swap back — before anybody is called about the ice maker. ## Where this fits in the ice diagnosis If your machine is making no ice, slow ice or small ice, the order is: - **Filter** — date, and whether it is genuinely seated.- **Shut-off valve** — behind or under the machine, or beneath the sink. A valve half closed during some other work years ago produces this and nothing else.- **Freezer temperature** — measured with a thermometer between packages. An ice maker harvests on temperature, so a compartment two degrees warm stretches every cycle.- **Fill valve**, then the **ice maker module**. In that order, and only then. ::: Three of those four are free, and the part people replace first is fourth on the list. ## The honest limitation Ice is the one repair nobody can prove inside an appointment, because a machine takes hours to fill a bin. What can be proved on the day is the **fill** and the **harvest** — and after that, you should be told exactly what to expect by the evening rather than being assured it is fixed at the door. --- **[Read full article: Changing the Water Filter: the Part Behind Three Different Ice Complaints](https://fisherpaykelmiami.support/blog/fisher-paykel-water-filter-change/)**
