The short answer
On the Avanti XQB models here the drain path is short: tub, pump, hose, standpipe. On a compact top-loader the cabinet is lighter than the load it spins, so anything that upsets the balance moves the whole machine. Four places, checkable in order, and the first two account for most of what gets reported.
What you observe on these models
- Water sits in the tub at the end of the cycle — The defining symptom.
- The pump runs but nothing leaves — A pump that is audible and ineffective has an obstruction or is moving foam instead of water.
- Water rises in the standpipe instead of going away — That is the house drain, not the machine, and it will affect the sink beside it too.
- It drains slowly rather than not at all — Slow is a restriction: a partly blocked filter, a kinked hose, or a hose lifted too high.
- NEAR MISS — it drains fine but will not spin — That is a lid-switch or balance fault, which is a different page.
Causes, most likely first on XQB
- The pump filter or a blockage at the pump — This is the first check and the most common cause. Debris arrives at the filter by design; the design assumes someone empties it. Ranked first on Avanti XQB because these models carry very little electronics, so suspicion falls on plumbing, switches and the load long before it falls on a board.
- The drain hose — kinked, too high or pushed too far down — A hose crushed behind the machine, lifted above its maximum height, or pushed so far into a standpipe that it siphons, all present as a machine that will not drain properly.
- The lid switch gating the spin — On a top-loader the spin will not run with the lid reading open, so the water never leaves even though the pump is healthy.
- The pump itself — A pump that hums without moving water, or that is silent when it should run, has failed or has an obstructed impeller.
- The house drain the machine empties into — A restricted standpipe backs up and the machine appears to be at fault. The tell is water rising in the standpipe rather than staying in the tub. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Start at the pump — Watch a cycle from the lid with the machine loaded as the owner loads it — on this class of machine the load and the hose run explain more faults than the parts do. Expect water; have towels ready.
- Straighten and re-route the drain hose — Look behind the machine for a crush, and check the height the hose discharges at. Too high and the pump cannot lift it; too far into the standpipe and it siphons.
- Listen for the pump at the drain step — Silence means no supply or a failed pump; a hum with no movement means an obstructed impeller.
- Ask about detergent quantity — Excess foam defeats a pump completely and leaves it apparently running. It is free to test — one cycle with half the usual dose.
Before you open anything
Safety
Unplug the washer or switch off its breaker before removing any panel, and close the tap before touching a fill hose. A capacitor can hold a charge after the power is off. Have a shallow tray and towels ready before opening any filter: a full tub empties fast and a wet floor beside a machine you are about to move is how people get hurt.

When to call a technician
Call when the filter is clear, the hose is properly routed at the correct height, the standpipe takes a bucket of water freely, and the pump either does not run or hums without result. Call sooner if you find water at the outlet or the machine has tripped protection. On Avanti XQB the filter and the hose routing between them explain the clear majority of no-drain reports, so do those first whatever else you plan. Check the plate before acting on any of this. XQB is a coded-line compact top-load washer, and the ranking above is written for that construction rather than for the brand as a whole.
