HAVA R09 dishwasher salt: use the dedicated chamber
HAVA R09 has a dedicated softener chamber for dishwasher salt. Its manual gives a 250–500 g fill range, specifies cold water when the chamber is dry, and calls for an empty wash afterward. The salt light can remain on while the salt dissolves.
Salt is not another form of detergent
The salt supports the R09’s water softener; detergent cleans the dishes. Put each only in its designated place. Do not use table salt or pour softener salt loose into the wash chamber. This advice applies to R09, not to every HAVA dishwasher: R01 lacks the same salt system.
Read the chamber instructions before opening the bag
- Locate the softener chamber using the R09 manual’s diagram. Check that you have dishwasher-specific salt.
- Follow the manual’s 250–500 g range without overfilling. If the inside is dry, use cold water as instructed; the manual excludes warm or hot water for this step.
- Stir gently as directed and securely close the cap. Avoid leaving spilled salt in the tub.
- Run the instructed empty wash after filling. Do not treat this as a reason to wash a load of dishes immediately with loose salt present.
Read the matching manual alongside this checklist; it is not a replacement for the illustrated filling procedure. A bag’s total weight is not an instruction to empty the entire bag into the chamber.
Choosing a hardness setting
The manual offers H1–H7 settings. Use actual information about your water supply and match its units to the table. “My area has hard water” is too vague to choose a number accurately. If a household softener already changes the water reaching the appliance, the raw municipal report may not describe that final supply.
Ask HAVA for help if your water information or manual version does not map clearly to the table. We do not assign every reader the same setting or claim that maximum softening is always best.
Match your water result to the R09 setting.
The table below follows the US-linked R09 manual, printed page 13. Check the units on your water report first: these columns express hardness as calcium carbonate (CaCO₃). Do not put a grains-per-gallon number directly into an mg/L column.
Swipe or scroll sideways to see every column on a small screen.
| Setting | Hardness: mg/L as CaCO₃ | Hardness: mmol/L as CaCO₃ |
|---|---|---|
| H1 | 0–10 | 0–0.10 |
| H2 | 11–100 | 0.11–1.00 |
| H3 | 101–200 | 1.01–2.00 |
| H4 | 201–300 | 2.01–3.00 |
| H5 | 301–450 | 3.01–4.50 |
| H6 | 451–650 | 4.51–6.50 |
| H7 | Above 651, as printed | Above 6.51, as printed |
The manual prints “>651” and “>6.51” for H7. That leaves the exact boundary unclear. If your result is on an unassigned boundary, between the printed bands, or in a different unit, ask HAVA to confirm the appropriate setting rather than rounding to a guessed choice.
Change the setting using the R09 controls
- Hold Power + Child Lock together for five seconds to enter the setting control.
- Press Child Lock briefly to move through the settings.
- When the required H number appears, briefly press Power to confirm.
These are R09 instructions, not an R01 button sequence. A salt refill and a hardness setting are separate jobs; refilling does not tell the machine your local water hardness.
Can R09 run without salt?
The manual describes salt use as optional. HAVA’s US FAQ says the R09 can operate without it, with the salt indicator remaining illuminated, and recommends using salt with hard water. That does not mean you should ignore a new error code or use a substitute salt.

Why the salt light may stay on
A light immediately after filling is not proof that the fill failed. HAVA explains that the indicator may remain illuminated until salt dissolves. Do not repeatedly top up past the chamber’s allowed level in an attempt to turn it off. If it persists beyond the expected operation, record the filling steps and contact support rather than bypassing the indicator.
Is the R09 worth choosing for this feature?
The softener is a meaningful difference for someone whose water and care routine make it useful. It also adds a consumable and a setting to maintain. It does not prove the R09 cleans better in our testing—we have not tested it—or guarantee that every cloudy mark on glass will disappear.
Questions that come up next
Can I use ordinary cooking salt?
Use the dishwasher-specific salt required by the R09 manual, not a kitchen salt substitute.
Should I buy R09 just to avoid all spots?
No model-specific feature guarantees spot-free results. Water, detergent, dishes and loading still matter; compare the whole installation and routine.
Your next useful step
If a built-in softener matters to your purchase, compare R09 with R01 before choosing the upgrade.
