Maytag MDB4949SKZ Dishwasher: Problems & Fixes

Which models this covers#

Built from 2019 to 2025, the MDB4949SKZ variants share one parts catalog:

• MDB4949SKZ
• MDB4949SKZ0
• MDB4949SKZ2

They sit on the MDB4949 platform; the standard-stainless MDB4949SHZ is mechanically identical, differing only in door finish.

Error codes#

• Error F8 E1 — click for full diagnosis and fix
• Error F2 E2 — click for full diagnosis and fix

For a code not listed, unplug the unit for 60 seconds, then restore power. A transient fault clears; a returning one needs a proper diagnosis.

Recall status#

There are no active recalls on the MDB4949SKZ series as of 2026-05-28. Check cpsc.gov against your model number periodically, since a recall can be issued at any time.

Repair or replace?#

The usual threshold applies: under 10 years old with a fix below 50% of a comparable new dishwasher favors repair; past 10 years, weigh the total repair history before spending more. The impeller, inlet valve, and dispenser latch are all straightforward, cost-effective repairs.

Before you call — quick checks#

Clean the Dual Power Filtration system at the bottom of the tub every one to two weeks. Confirm the water-supply valve is fully open, and run the sink's hot water before starting a load. If detergent is not releasing, make sure nothing in the lower rack is blocking the dispenser door.

Cleaning the Dual Power filter#

Pull the lower rack and spray arm, twist the cylindrical filter counter-clockwise, and lift it out. Separate the upper filter from the lower plate and rinse both under warm water with a soft brush. Never use a wire brush. Reseat and twist to lock, and clean every one to two weeks so the system does not recirculate debris onto your dishes.

Common questions#

What is the difference between the SKZ and SHZ? Only the door finish — the SKZ has the fingerprint-resistant PrintShield stainless, while the SHZ is standard stainless. The pump, motor, and controls are identical.

Is it quiet enough for an open kitchen? At 50 dBA it is audible during a cycle — comparable to moderate rainfall or a quiet office. For near-silent operation, look at units in the 42–46 dBA range.

Telling the top faults apart#

The impeller and inlet-valve failures produce opposite symptoms that are easy to distinguish. A broken drain-pump impeller leaves standing water because the pump cannot push it out, while a failed inlet valve leaves the tub dry because no water arrives in the first place. The dispenser-latch fault is minor by comparison — detergent simply is not released mid-cycle, often because something in the lower rack blocks the door. The grounded heating element deserves the most caution: it can trip the breaker, so if heated dry coincides with a tripped circuit, stop using the machine until the element is replaced. Sorting symptoms this way tells you whether you are facing a five-minute check or a genuine part replacement.
