Quick answer: Error i20 on a Westinghouse dishwasher means a drainage fault — the machine could not empty within its programmed drain time. In the vast majority of cases a blocked filter or a kinked drain hose is the cause, and the fix is free and takes under fifteen minutes. If the filter, hose and sink connection are all clear, the drain pump has failed. A replacement drain pump costs $29.95–$38.95. Some panels show the same fault as C2, F20 or Er2.

What the Westinghouse i20 code means
Westinghouse dishwashers sold in Australia are built on the Electrolux platform and use i-series fault codes: the i20 code fires when the water level has not cleared during the drain phase. Depending on the control panel style, the identical fault may display as C2, F20 or Er2 — the cause and fix are the same.
Confirm your exact model on the model sticker on the inner door edge before ordering parts. The full code list is in our Westinghouse dishwasher error codes guide.
Common causes of Westinghouse i20
| Cause | Likelihood | Fix |
|---|---|---|
| Filter and sump blocked with food debris | Very common | Remove and rinse filters — free |
| Kinked or pinched drain hose | Common | Straighten hose — free |
| Blocked sink waste spigot (or knock-out plug never removed) | Common | Clear the spigot / remove the plug — free |
| Debris jamming the pump impeller | Less common | Remove obstruction from the sump — free |
| Drain pump failed electrically | Less common | Replace drain pump — $29.95–$38.95 |
How to fix the Westinghouse i20 error — step by step
- Cancel the programme and disconnect power at the wall socket. Bail out any standing water with a jug and towels.
- Remove and clean the filters. Pull out the bottom rack, twist the cylindrical micro-filter a quarter-turn anticlockwise and lift it out along with the flat mesh filter beneath. Rinse both under running water and scrub lightly.
- Inspect the sump and impeller. Shine a torch into the sump cavity and remove any glass chips, bone fragments or debris jamming the impeller.
- Check the drain hose. Pull the machine forward and trace the hose to the sink connection. Straighten kinks and confirm the anti-siphon high loop is intact.
- Check the sink waste spigot. Confirm the dishwasher branch is open and grease-free, and that the knock-out plug was removed at installation.
- Run a short rinse programme. If i20 returns and the pump is silent (or hums without moving water) during the drain phase, the pump has failed — replace it.
Tip: Because Westinghouse dishwashers share the Electrolux platform, the same drain pump is often listed under Westinghouse, Electrolux and Dishlex names. Match on your model number and the pump listing’s stated fitment, not the brand on the front of the machine.

Frequently asked questions
Does i20 always mean the drain pump is dead?
No — the majority of i20 faults are cleared by cleaning the filters and straightening the hose without spending a cent. Replace the pump only after everything upstream is confirmed clear.
My panel shows Er2, not i20 — is that the same fault?
Yes. Some Westinghouse control panel styles use an Er prefix: Er2 is the same drainage fault as i20 (and C2 / F20 on other panels). The fix is identical.
The machine drains a little then stops with i20 — what does that suggest?
Partial draining usually points to a partial blockage — typically compacted debris in the sump or a half-blocked sink spigot — rather than a dead pump.
Where is the model number on my Westinghouse dishwasher?
On the model sticker on the inner door edge, visible when the door is open.
