AEG dishwasher won't start...I turn it on, it makes a little noises but the water doesn't start flowing. the noise comes from the bottom, in the area of the filtter.

Error "i30" means that water remains in base because leakage or overflow. In this case, in order to prevent flooding, drain pump running continuously.
When we talk about AEG dishwasher, drain pump works even the power is turned off (must be connected to the wall outlet, otherwise anti-flooding system will not work).
The noise what you heard during operation indicates that something is blocking the drain pump.
Remedy: you should first remove the water from the bottom of the dishwasher and determine leakage then check why the drain pump makes noise.

If you work around the dishwasher, you always take care that appliance must be disconnected from the power supply.

Good luck.

When you start a wash cycle on your Bosch dishwasher and it does not work, stay calm. It could be something simple, especially if you just installed it. Make sure the power cord is connected properly and a circuit breaker did not trip. How to Troubleshoot Bosch Dishwasher That Doesn Fill With Water

Hello

When an appliance such as a dishwasher starts making a new noise, you need to isolate the cause of the noise so that you know whether or not it is damaging the machine. Several things can cause a noisy dishwasher.

Motor

Dishwashers are driven by an internal motor that gets quite noisy when defective. The problem occurs when a seal breaks down and allows water to access the bearings in the motor, removing the grease needed for proper lubrication and creating a loud motor noise when the dishwasher runs. The seal or bearings need to be replaced in this situation quickly or more extensive damage to the motor may occur.

Inlet Valve

If the inlet valve on your dishwasher is broken or breaking, you will hear a distinctive thumping or clattering noise whenever a load is run. A thumping noise doesn't always indicate this problem, however, depending on when you hear it. If you hear a noise like this when the water is filling up the dishwasher at the start of the cycle, the noise likely points to an inlet valve problem.

Squealing

A high-pitched squealing noise is an indication that something is wrong with the fan. Fan bearings that are worn out indicate that the fan apparatus needs to be replaced. If the noise you're hearing is in fact coming from the fan, it will only occur when the dishwasher is drying the dishes. Dishwashers use a fan to generate and distribute heat to dry the dishes quickly.

Minor Concerns

Sometimes even a minor concern can cause a great deal of noise. The thing to watch for is whether or not the noise repeats itself on multiple loads. A loud noise on a single load that doesn't repeat could be caused by things like a loose utensil or small implement rattling around loose in the dishwasher. Also inspect the bottom of your dishwasher. Hardened bits of old food can become rock hard under the heat in the dishwasher and cause noise when the unit runs.

Check the nozzle to see if is plugged. If water can" pass thru , it won't read a water pressure drop and turn on the pump motor.

dead battery, charge it.

This is caused by a partially blocked valve or inlet, it is a little blocked, and this sound you hear is the air pushed through it making a sound. You need to clean out the inlet valves.

the arms are only turned by water coming out of them thro angled jets, they are not electrically driven. the noise will be coming from the circulating pump, probably one of the bearings. no cure except to replace
