Whirlpool WDPA70SAMZ2 dishwasher Parts

A “quiet” dishwasher is typically 44 dBA or lower; ultra-quiet models can run in the high-30s dBA range. For your Whirlpool WDPA70SAMZ2, the exact sound rating depends on the specific build and insulation package, but 44 dBA is the common quiet benchmark.

Quick dBA guide (what you will notice)

• 38 to 41 dBA: very quiet; often hard to hear in an open kitchen
• 42 to 44 dBA: quiet; normal conversation easily covers the sound
• 45 to 49 dBA: moderately quiet; you will notice it in a quiet room
• 50 dBA and up: average to louder; more noticeable wash and drain sounds

Why dishwasher noise varies

Even at the same dBA rating, real-world noise can change based on installation and use:

• Loose mounting or cabinet contact can amplify vibration
• A kinked or vibrating drain hose can add a buzzing sound
• Hard items (pots, utensils) touching the spray arm can rattle
• A worn rack can let dishes shift and clink
• Water pressure and drain flow can change fill and drain sound

Common “too loud” causes and what to check first

Symptom	Most common cause	What to do
Rattling/clanking	Dishes contacting each other or the spray arm	Reload so items do not touch; secure light plastics
Buzzing during drain	Drain hose vibrating	Reposition and secure the hose; check for kinks
Thumping/knocking	Spray arm hitting a tall item	Move tall items to the sides or upper rack
Vibration/hum	Dishwasher not firmly fastened	Refasten to the cabinet or floor

Why it matters

Lower dBA usually means better insulation and smoother wash system operation, which makes the dishwasher easier to run overnight or during meals. If your WDPA70SAMZ2 suddenly gets louder, it often points to a loading issue or a part starting to wear.

Yes. The Whirlpool dishwasher model WDPA70SAMZ2 is discontinued, which means it is no longer being manufactured or sold as a new unit. You can still keep it running by replacing worn or failed components using the parts listed for this model, such as the latch assembly (includes switch) W11412299.

What “discontinued” means for repairs

A discontinued model can still be a great candidate for repair. In most cases:

• Replacement parts remain available for years after production ends.
• Common wear items (door seals, racks, valves, hoses) are typically the first parts customers replace.
• Some cosmetic items (panels, caps) can become harder to find over time.
• Using the correct model number (WDPA70SAMZ2) helps ensure part compatibility.

Quick checks before you order parts

If you are troubleshooting a symptom (won’t start, won’t fill, leaks, won’t drain), we recommend these basics first:

• Confirm the door closes and latches firmly (a bad latch can prevent starting).
• Check for standing water and a kinked drain hose.
• Look for water at the bottom edge of the door (seal issues).
• If the dishwasher won’t fill, verify the water supply valve is on.
• If you see an error code, match it to the correct Whirlpool family.

For code-based troubleshooting, use our how to reset a Whirlpool dishwasher steps first, then reference the appropriate Whirlpool error code guide.

Common parts customers replace on WDPA70SAMZ2

Symptom	Likely area	Example part on this model
Won’t start or stops mid-cycle	Door latch/switch	Latch assembly (includes switch) W11412299
Won’t fill or fills slowly	Water inlet/fill system	Fill valve assembly W11434044
Leaks at the bottom of the door	Door sealing	Seal, door bottom W11664713
Not draining	Drain path	Hose-drain,e W11414944

Why it matters

Knowing WDPA70SAMZ2 is discontinued sets expectations: you are shopping for replacement parts, not a new unit. The good news is that targeted repairs (like a latch, fill valve, or door seal) often restore normal washing performance quickly and cost-effectively.

On the Whirlpool WDPA70SAMZ2 dishwasher, the filter is in the bottom of the tub, directly under the lower dishrack. Pull the lower rack out to access the filter area, then remove and clean the filter so water can circulate and drain properly.

How to access and clean the filter

1. Turn the dishwasher off.
2. Slide the lower rack out.
3. Locate the filter assembly in the sump area at the bottom center of the tub.
4. Unlock and lift the filter out (most Whirlpool filters twist to release).
5. Rinse under warm water and scrub gently with a soft brush.
6. Reinstall the filter fully seated and locked, then reinstall the rack.

Quick tips (what we see most often)

• Clean the filter when you notice gritty dishes, cloudy glasses, or slow draining.
• Check for labels, glass, or food debris around the filter and sump.
• Avoid running without the filter installed; it can damage the wash system.
• If the lower rack blocks access or is damaged, inspect the dishwasher dishrack, lower W10728159.
• If you still have standing water after cleaning, follow a drain troubleshooting guide like dishwasher not draining video.

What “filter” problems look like

Symptom	Common cause	What to do first
Food bits left on dishes	Filter clogged	Clean filter and sump area
Dishwasher smells	Debris trapped in filter	Clean filter; run a cleaning cycle
Water left in bottom	Drain path restricted	Clean filter; check drain hose routing
Poor spray	Debris recirculating	Clean filter; check spray arm holes

Why it matters

A clean filter helps your WDPA70SAMZ2 maintain strong wash pressure, prevents debris from recirculating onto dishes, and reduces the chance of drain issues that can trigger error codes.

On Whirlpool dishwashers like model WDPA70SAMZ2, the most common service issues are not draining and poor cleaning, usually caused by a clogged drain path, debris in the sump area, or restricted spray arm flow. Leaks and no-start problems are also common and often trace back to seals or the door latch.

Most common symptoms and likely causes

• Won’t drain: drain hose restriction, debris in sump, drain path blockage
• Not cleaning well: clogged spray arm holes, circulation restriction, loading issues
• Leaking: worn door seals or tub gasket, loose connections
• Won’t start/stops: door not latching, latch switch not closing, control issue
• Fill problems: water supply issue, inlet valve problem, float switch stuck

Quick checks we recommend first

• Reset power (turn off for 1 minute, then restart) and try a normal cycle.
• Confirm the door closes fully; racks or tall items can prevent a solid latch.
• Check the drain hose for kinks and make sure the sink or disposer connection is clear.
• Clean the bottom area (sump) and rinse out any visible debris.
• Run hot water at the sink for 30 to 60 seconds before starting.

Model-matched parts to check on WDPA70SAMZ2

Symptom	Part to check	What it affects
Won’t start	Latch assembly (includes switch) W11412299	Door-closed sensing and cycle start
Not draining	Hose-drain,e W11414944	Drain flow out of the dishwasher
Not filling	Fill valve assembly W11434044	Water entering the tub
Overfilling/no fill	Dishwasher float switch W11545764	Water level control
Leaking at door	Seal, door bottom W11664713	Seals the lower edge of the door

Why it matters

Drain and wash problems can look similar; a dishwasher that “won’t run” may actually be failing to fill or sense a closed door. Matching the symptom to the right system helps you replace the correct part the first time.

For code-based troubleshooting, use Whirlpool dishwasher error codes.
