Issue

• Dishwasher displays error code i20 or F2
• The dishwasher beeps 2 times, LED flashes 2 times
• My dishwasher is showing an error code and not draining
• Water drainage problem in the dishwasher

Applies to

• Dishwasher

Solution

1. Make sure that the sink spigot is not clogged.

2. Make sure that the interior filter system is not clogged. Check your dishwasher filter and sump are clean.

Refer to the instructional video

3. Ensure that the drain hose has been installed correctly (see image below):

• The length of the drain hose does not exceed 400 cm.
• The drain inlet point must be between 40 and 85 cm.
• The drain hose is not damaged, kinked, or twisted.

4. Check whether the blanking plug has been removed from the sink drain. (If your dishwasher has been recently been installed or moved)

The blanking plug must be removed from the siphon trap. Open the inlet where the drain hose is connected to the siphon trap, remove the blanking plug or if no plug, it must be drilled using a 10mm drill bit. Reconnect the siphon trap inlet (see image below)

Plug it back in. Turn on the dishwasher, select a suitable cycle and start it.

If the cycle starts and operates normally, the problem has been resolved.

If the above steps don't resolve the issue, we recommend contacting an Authorized Service Center.
