Summary

AEG FSB73427Z error code i10 means the dishwasher has a water inlet problem and is not filling correctly. This guide follows the official AEG troubleshooting order so you can check supply, hose, filter, drain routing, and installation issues before calling support.

Fix it fast

  1. Check that the water tap feeding the dishwasher is fully open.
  2. Make sure the inlet hose is not kinked, twisted, or trapped behind the appliance.
  3. Turn off water and power, then inspect and clean the inlet hose filter at the tap connection.
  4. Run a fresh programme after reconnecting everything securely.

What i10 means

On the AEG FSB73427Z, i10 means the dishwasher is not filling with water as expected. AEG links this to water supply, inlet hose, inlet filter, drain routing, or installation issues such as a blanking plug still left in place.

Common symptoms

  • The dishwasher beeps once or shows i10 shortly after the programme starts.
  • Little or no water enters the tub.
  • The cycle stops early and the machine may drain before showing the code.

Most likely causes

  • Water tap is closed or household water pressure is too low.
  • Inlet hose is kinked, twisted, or damaged.
  • Filter in the inlet hose is clogged with debris or scale.
  • Drain system is routed incorrectly or recently installed with a blanking plug still in place.

Official AEG checks to do next

  1. Check household water flow by opening a nearby tap. If there is no water, contact your water supplier.
  2. If several appliances are using water at once, test the dishwasher again when the demand is lower.
  3. Use AEG’s pressure check: see whether one tap can fill a 5-litre bucket in 30 seconds. If not, pressure is too low.
  4. Inspect the inlet hose and replace or service it if it is bent, twisted, or physically damaged.
  5. Clean the inlet hose filter, then reconnect the hose and rerun a programme.
  6. Check the drain hose routing: maximum length 400 cm, drain inlet point between 40 and 85 cm, and no kinks or twists.
  7. If the dishwasher was recently installed or moved, make sure the blanking plug has been removed from the sink siphon connection.

Common mistakes

  • Resetting the dishwasher repeatedly without checking the tap or inlet hose first.
  • Cleaning the tub filters but forgetting the small inlet filter at the tap connection.
  • Ignoring a recent installation change where a blanking plug may still block the drain connection.

What not to do

  • Do not keep running the appliance if the inlet hose is damaged.
  • Do not remove hoses while the water tap is still open.

Safety warnings

  • Shut off the water supply and isolate electrical power before removing the inlet hose or filter.
  • If the hose is damaged, AEG recommends engineer inspection and repair rather than continued use.

When to contact AEG support

Book service if the machine still shows i10 after the official supply, hose, filter, drain, and installation checks, or immediately if the inlet hose is damaged. AEG explicitly recommends an approved service provider when the above checks do not resolve the issue.

How to help prevent i10 from returning

  • Keep the inlet filter free from limescale and debris during routine maintenance.
  • Avoid trapping or sharply bending the inlet and drain hoses when pushing the dishwasher back into place.
  • After installation or moving the appliance, recheck the sink connection and drain routing before first use.

FAQ

Does i10 always mean the water tap is closed?
No. AEG groups i10 with several water inlet causes, including low pressure, a kinked hose, a clogged inlet filter, or an installation problem.
Can low water pressure really trigger i10?
Yes. AEG’s own check is whether a single tap can fill a 5-litre bucket in 30 seconds; if not, the pressure may be too low for the dishwasher to fill correctly.
Why does AEG tell me to check the drain system for i10?
Because poor drain routing or a blanking plug left in the sink connection can interfere with normal water flow and installation behaviour, especially after recent fitting or moving.
