Re: ISE 5 Dishwasher : code F2
F2 is no drain detected in the time allowed, so a drain pump blockage is entirely possible. If you wish to deal with this yourself, power off, and bail out as much water as possible before removing the drain pump motor from underneath to find any foreign body.
You are well within the guarantee period, so a call to your ISE agent is your other course of action, Be advised that if the machine is blocked due to an inappropriate object, you may be charged.
