Ariston Dishwasher LD87, error code AL03

It sounds like there may be a problem with your Ariston dishwasher. The flashing lights and the dishwasher's inability to wash could be caused by a number of issues, including a problem with the control panel, a faulty water inlet valve, or a clogged wash pump.
To troubleshoot the issue, you can try the following steps:

1. Check the control panel for any loose or damaged wires. If you find any loose or damaged wires, try to secure them or repair them as needed.
2. Check the water inlet valve to make sure it is not clogged or faulty. The water inlet valve controls the flow of water into the dishwasher. If it is clogged or faulty, it could cause the dishwasher to stop working.
3. Check the wash pump for any blockages. The wash pump is responsible for circulating the water during the wash cycle. If it is clogged, it could prevent the dishwasher from washing properly.

might be a control board problem

I found a very good page for this problem on the internet - http://www.almesberger.net/ld87/al03.html -
After reading that page, I knew exactly what to do. In my case, something had stopped the pump from working, So I could solve the problem without removing the pump.

You don't put salt in a dishwasher unless you want to ruin it.

2. You ONLY use a detergent specifically for dishwasher use as the cleaning agent and you 3/4 fill the soap dispenser in the washer (normally fitted into the door on the inside) with the dishwasher powder.

3. If there is a separate small compartment in your dish washer for a "rinse aid" solution to be used, you can use a rinse aid product designed for dishwasher use only. If there is no rinse aid compartment (this is also normally fitted to the inside of the door - if fitted on your machine) then you cannot use a rinse aid in your washer.

4. Don't use any other product in the dish washer.

This option can be selected by pressing the corresponding button, and remains in memory until the same
button is pressed again. This option modifies the phases of the programme in order to optimize performance
when "3 in 1, 5 in 1, 7 in 1, ......." detergent tablets are used:

- variation of the duration of the programme and the temperatures required to dissolve the detergent tablets.
- reduction of water exchange
- exclusion of introduction of rinse-aid
- exclusion of regeneration

If you use a dishwasher in the traditional manner (detergent, rinse aid, salt) then the Multitab function is disabled. If you use tabs that are already on the market with rinse aid and salt there is a possibility during washing cycle to add a double dose of rinse aid. From rinse aid dispenser and rinse aid from tabs. This will lead to poor cleaning results, glasses will look like they have been washed in milk..To avoid that you must turn on "Multitab" function and thus exclusion of introduction of rinse-aid from rinse aid dispenser. This function also stops the regeneration and will not spend salt because salt is already in a tabs. Also extends the washing time because tablets need more time to dissolve in relation to the traditional powder detergent.

The top light is apparently to indicate that the salt (!) has run out.

The bottom light is apparently to indicate that rinse aid has run out.

For the record, that seems to be a Zanussi DE-6854 dishwasher, and I found the manual here: (link)


"Special salt can be added in one of two ways: 1) If you are using dishwasher detergent that already contains salt, the detergent including the salt is placed in the detergent compartment. - In this case the water softener must manually be set to 1 and electronically to 1 to ensure that the special salt is taken from the detergent container only. 2) If you are using dishwasher detergent and salt separately, the special salt is to be put into the salt container. - In this case the water softener must manually be set to 1 or 2 and electronically between 1 and 5 (depending on the water hardness in your area) to ensure that the special salt is taken from the salt container only. Only use salt specifically designed for use in dishwashers. All other types of salt not specifically designed for use in a dishwasher, especially table salt, will damage the water softener. Only fill with salt just before starting one of the washing programmes. This will prevent any grains of salt or salty water, which may have been spilt, remaining on the bottom of the machine for any period of time, which may cause corrosion." (Page 6)

"Only use branded rinse aid for dishwashers. Never fill the rinse aid dispenser with any other substances (e.g. dishwasher cleaning agent, liquid detergent). This would damage the appliance." (Page 7)

The manual also explains how to turn the Rinse Aid light off permanently if you do not wish to use rinse aid.



Good luck!

The most common cause of film left behind is a broken heating element.

The heating element is not only used during the dry cycle, but also to raise the water temp. during the main wash cycle to activate the dishwasher detergent. Fixing the heating element should "clear" this problem right up!
