Hi

Thanks for using FixYa. F1 error means that the flood switch has been activated. You’ll need to reset it by powering off the breaker or by unplugging the unit from the power socket and mains for more than five minutes. Please check that there is no blockage in the drain hose and it is not raised higher otherwise the water will run back to the dishwasher. Also perform the following procedure---

• Unplug power and remove bottom dish drawer
• Use a Sponge and dry all the excess water underneath
• Remove circuit board cover
• Dry all around and underneath as much as possible
• Apply hairdryer for 10-15min
