Description

The water filter cartridge removes impurities from the water supply before it reaches the dispenser tap and the ice maker.

It sits in a housing at the top corner of the fridge compartment on the models listed here, and it is a twist-fit cartridge that locks into place with a quarter turn.

Inside the cartridge is a block of activated carbon and a mechanical filtration membrane; together, they remove chlorine and its associated taste and odour, sediment and particulate matter, lead and other heavy metals, and a range of trace contaminants, including pharmaceuticals and microplastics. The result is clear, fresh-tasting water and ice, plus protection for the dispenser valve, water lines, and ice maker from the scale and sediment that would otherwise build up inside them.

A water filter is a consumable, and it degrades gradually rather than failing suddenly. The first sign is usually a change in the taste or smell of the water, or a slow reduction in the flow rate at the dispenser as the carbon block becomes saturated and the membrane clogs. In hard water areas, this happens faster because limescale collects in the cartridge. Continuing to use a spent filter means the water is no longer being properly treated, and the dispenser and ice maker are left unprotected from scale and sediment.

Frost in an unheated outbuilding and high water pressure can also damage the filter housing and cartridge, causing the cartridge to crack and leak. Replacing the filter at the recommended interval keeps the water quality high, the flow rate steady and the dispenser and ice maker working as they should.

Product code: 2420580.

Fitment guidance: This filter is compatible with the Hisense models listed below. The model number is found on the rating plate, which is normally located inside the fridge compartment on the left-hand wall, behind the salad crisper, or on the rear of the cabinet. Match the complete model number exactly. The filter is located in the top corner of the fridge compartment and is removed by turning it a quarter turn counter-clockwise and pulling it out of the housing. Before ordering, confirm that your appliance uses the twist-fit internal cartridge and not an inline filter or a different housing type, as Hisense produces several filter designs across its ranges.

Diagnostic tip: If the dispenser flow has slowed noticeably, or the water tastes or smells unpleasant, the filter is the first component to check. Remove the cartridge and inspect the housing and the cartridge for cracks, scale or debris. If the filter has been in use for more than six months, replace it regardless of symptoms. If the dispenser flow is still poor with a new filter fitted, check the water supply pressure and the condition of the water line and the dispenser valve. If the filter housing itself is cracked or leaking, the housing will need to be replaced rather than the cartridge. A filter that has frozen, usually because the appliance is in an unheated space, will be cracked and must be replaced.

Installation guide: 1. Switch off the water supply to the appliance at the isolation valve or the mains stopcock. 2. Open the fridge door and locate the filter housing in the top corner of the compartment. 3. Turn the old cartridge approximately a quarter turn counter-clockwise until it releases, then pull it out of the housing. 4. Have a towel or shallow container ready, as a small amount of water will escape when the cartridge is removed. 5. Remove the protective cap from the new cartridge. 6. Line up the ports on the top of the new filter with the ports in the housing and insert it gently. 7. Turn the cartridge approximately a quarter turn clockwise until it stops and locks into place. 8. Restore the water supply and check the housing and cartridge for leaks. 9. Flush the system by dispensing around 5 minutes of water through the dispenser to clear any carbon fines. 10. Reset the filter indicator on the control panel by pressing and holding the appropriate button combination for your model, usually the Ice On/Off button for 3 seconds.

Safety note: Always turn off the water supply before removing the filter cartridge. Do not use the appliance with the filter housing empty or the cartridge loose, as water will leak. This filter is for cold water only and must not be used with water that is microbiologically unsafe or of unknown quality without adequate disinfection. Dispose of the spent cartridge responsibly. If the filter has frozen, do not attempt to thaw and reuse it, as the internal membrane will have been damaged.
