Dishwasher Electrolux ESF 4159 i10 and IFO error - what to change

Hello,

I have a problem with the dishwasher, at some point it stopped heating, I replaced the heater without checking for errors, then I deleted the errors (i10 and IFO) from the memory. The dishwasher heated the water once and stopped heating again. I cleared the errors again and the dishwasher spilled water through the door during the test cycle.

Description of the given errors:

Code "i10": displayed during static filling
This alarm code signals the closure of the water tap when starting the program. It allows you to detect problems during the static water filling. Before the alarm is displayed to the user, the purge phase is performed.
o Audible signal and visual alarm, depending on device configuration; possibility to restart the program.
o Failure to reach the specified water level within the specified time.
o The timeout countdown begins when the fill solenoid opens.
o The timeout is reset when the fill solenoid closes.
o The water will be drained before the error is displayed to the user.
o Timeout: normal cycle: 90 s; test cycle = 30 s (values may differ as they are determined by the MCF system).

Code "iF0" - group: overflow detection
o The alarm will be saved and displayed only in service mode; the program will continue.
o This error occurs when the total fill time has exceeded the limit.
o The time is counted with each subsequent filling process and reset each time the evacuation system is triggered.
o If an alarm is detected, the heater will not be turned on and subsequent fillings will be skipped.

None of the hoses reaching the hydrostats (?) Are clogged, they are under tension. I have no more ideas how to bring the dishwasher back to life, please help ...

iF0 - Water replenishment Time-out (3 times during the T.S. Time-out)
- T he cycle continues until the next phase without supplementary fills
and without heating. The error is cancelled on completion of a drain phase.
- Dishes upside-down; central filter clogged; excessive foam; leaks from the sump-pressure
switch coupling; pressure switch faulty / false contacts.

i10 - (The pressure switch does not close on FULL after 90 sec. static fill, or never
closes on “FULL” during the initial 60 sec of the dynamic fill at 2800 rpm)
- The drain pump switches on, then the cycle stops
- Tap closed; water mains pressure too low; fill solenoid / wiring faulty; hydraulic circuit of pressure switch obstructed;
level pressure switch / wiring faulty; circuit board faulty (solenoid triac shortcircuited)

I tu kolejna przewaga serwisu nad samonaprawiaczmi jest taka iż serwis podmieniłby elementy aby wykluczyć uszkodzenie. Sam pomiar i dmuchania w wężyki jest niemiarodajny.
Prąd do bezpiecznika w mieszkaniu też dochodzi a nie zawsze z bezpiecznika wychodzi.
Po za tym masz dwa hydrostaty w tej zmywarce.

So I understand that I should replace the hydrostats now. Are both technically the same? Visually, they are very similar, only attached differently. The harness is fine - no chafing or other signs of damage.

One more piece of information, during the test cycle, the first filling takes about 35-40s, the second about 100s, and the dishwasher draws water again. I did not wait for another disconnection for fear of spilling the water again.
