902979927 Genuine Electrolux Dishwasher Salt 1kg Pack for Dishwashers with a Built-In Water Softener

Electrolux dishwasher salt, part 902979927, comes in a 1kg pack for dishwashers fitted with a built-in water softener. The salt goes into a reservoir in the floor of the tub, usually under the lower basket, and the machine uses it to recharge its softening resin. It is made for the job, unlike table or cooking salt, which can contain additives that upset the softener.

Why your dishwasher needs salt

Hard water leaves calcium and magnesium deposits on glassware, the heating element and inside the pipes. Dishwashers with a water softener pass incoming water through a resin that captures those minerals, and salt is used to flush and recharge the resin. When the salt runs out the softener stops working, and you start to see white spots, a cloudy film on glasses, gritty residue on dishes and scale around the door and tub. Many machines show a salt warning light when the reservoir is low. How often you top up depends on your water hardness setting.

Filling the salt reservoir

Take out the lower basket and unscrew the salt cap in the floor of the tub. On the very first fill, many manuals ask you to add water to the reservoir before the salt. Use a funnel to pour salt in until full, wipe any spilt salt off the thread and tub, and screw the cap on tightly. Run a rinse or normal cycle straight away so stray salt does not sit in the tub and cause corrosion.

Questions about this part

Can I use table salt instead?

No. Table and cooking salt can contain anti-caking agents and iodine that may damage or clog the softener. Use salt made for dishwashers, like this Electrolux 1kg pack.

Does my dishwasher need salt?

Only if it has a built-in water softener. Look for a screw cap in the floor of the tub under the lower basket, or a salt setting in the manual. Machines without a softener do not need it.
