Last updated 24/03/2020 19:49

Issue

  • Dishwasher displays error message i30
  • Dishwasher drain pump runs constantly (background hum/rumbling noise low down)
  • Dishwasher leaking constantly 
  • Error code i30
  • The anti-flood device is on (hence pump running)

Applies to

  • Integrated dishwasher
  • Freestanding dishwasher

Resolution

Error i30 is caused by water (or foam) leaking from the dishwasher tub, into the base of the unit and activating the anti- flood sensor.  It is possible that after leaving the machine for several hours, or overnight ( with the water supply turned off), the error may disappear and the programme will run again.  However if the source of the leak into the base has not been rectified, it is likely the i30 error will return:  

Over foaming:

On some occasions, excess foam inside the tub can lead to incidents of i30. If this is the case, switch of the dishwasher at the mains, leaving it overnight to allow foam to disperse, then refer to our article 'Foam in my Dishwasher' for more advice on this topic. 

Spray arm rotation impeded or large item deflecting water jet:

Occasionally a large item may block or impede the spray arm rotation, leading to water being sprayed consistently in one position only, this may put undue pressure on one area of the door seal and lead to inundation and leaking in that particular area.  Check the loading and ensure the spray arms can rotate freely and that no unusually large item is either blocking movement, or perhaps deflecting water spray into a corner of the dishwasher, or back onto the internal door panel. After adjusting the load and/or removing the large item, leave the machine off overnight to allow the base to dry out a little and try again the next day. 


If the fault is not caused by over-foaming or the above advice does not rectify your issues, please contact us to arrange a repair. 

Error message i30 may indicate an internal leak leading to the water collecting in the base of the appliance. In this case a visit by an authorised service technician will be required.

Warning: Turn off the dishwasher's water supply to avoid any risk of flooding.
