i20: Water Not Draining

If your Zanussi dishwasher has displayed the i20 error code on its display panel, it's telling you that water isn't draining away properly at the end of the wash cycle. This is a medium-severity fault, but the good news is that many i20 issues can be resolved without calling out an engineer, saving you both time and money. The problem typically stems from one of three common culprits. Most frequently, debris has accumulated in the dishwasher's filter, blocking the water's path to the drain. Alternatively, the drain hose connected to your appliance may have become kinked or twisted, restricting the flow of water. Less commonly, the drain pump itself may have developed a fault, though this is less likely to be the cause. Before you worry about replacement parts, it's worth checking these components yourself. Start by inspecting the filter for blockages and ensuring the drain hose isn't bent or crushed behind your dishwasher. These simple checks can often identify the issue and get your appliance working normally again. If problems persist after these checks, the drain pump may require professional attention.

Many i20 faults can be resolved by a competent DIYer. Always disconnect from mains power first. If unsure, consult a qualified engineer.
