What the DW family is
A DW dishwasher is one platform sold under a handful of model codes, and the faults that actually arrive on it are the ordinary dishwasher four: it will not start, it will not drain, it leaks, or it stops cleaning properly. Drainage and cleaning complaints dominate, and both start at the filter — which is also the part nobody cleans.
What goes wrong
- It will not drain — Water stands in the bottom of the tub at the end of a cycle. See the DW page for this fault. — Slug: cove-cove-dishwasher-dw-dishwasher-drainage-failure — Title: Cove DW Dishwasher: Will Not Drain
- It leaks — Water in front of the door is the gasket, the levelling or over-sudsing; water underneath is the fill valve or the sump. See the DW page for this fault. — Slug: cove-cove-dishwasher-dw-dishwasher-water-leak — Title: Cove DW Dishwasher: Water Leak
- It stops cleaning or drying properly — Grit left on the dishes, film on glassware, or a load that comes out wet. See the DW page for this fault. — Slug: cove-cove-dishwasher-dw-dishwasher-cleaning-performance — Title: Cove DW Dishwasher: Does Not Clean or Dry
- It will not start — The panel lights but the cycle never begins, or the machine is dark altogether. See the DW page for this fault. — Slug: cove-cove-dishwasher-dw-dishwasher-wont-start — Title: Cove DW Dishwasher: Will Not Start or No Power
Most frequent first on the DW family
- It will not drain — Ranked first on the DW family — the filter and sump load up over months on any dishwasher, and this platform is no exception; it is the most frequent single complaint and the cheapest to put right.
- It leaks — Second — fourth and least common.
- It stops cleaning or drying properly — Third — second, and usually the same neglect seen earlier: a blinded filter starves the spray arms long before it stops the drain.
- It will not start — Fourth — third.

Owner work, and what is not
On the Cove DW dishwasher family the owner line is the lower access panel. Filters, spray arms, the door gasket, the drain hose and the connection under the sink are all reachable with the machine isolated and nothing removed.
