KitchenAid Coffee Grinder Replacement Parts: What to Buy and How to Install Them

Written by [Mike Chen, 6 years hands-on experience repairing small kitchen appliances. Last updated: July 2026.

My own mill choked mid-batch last month, leaving me with half-crushed beans. I briefly feared the main motor was dead. Thankfully, most daily issues stem from just four basic wearable items.

Those failures usually trace to the burr plates, glass jar, safety lid, or power cord. This guide covers finding the exact KitchenAid coffee grinder replacement parts you need. We will focus on both the KCG0702CS burr grinder and BCG111ER blade grinder. You will see exactly how to install them at home.

Which KitchenAid Coffee Grinder Parts Fail Most Often?

Four parts fail long before the motor quits. You will likely replace the burr plates, glass jar, safety lid, or power cord first. The burrs crush your beans. When those sharp metal edges dull over time, your daily output turns visibly coarse and uneven.

The glass hopper catches your fresh grounds. It forms hairline cracks or chips near the base from repeated daily tapping. Meanwhile, the top safety lid acts as a vital power interlock switch. If that small tab snaps, the machine stays completely dead.

The thick cord feeds power directly to the heavy motor base. It slowly frays. The rubber casing eventually breaks near the plug from constant bending against the kitchen wall. Buying KitchenAid coffee grinder replacement parts resolves these exact headaches fast.

Part	Common Symptom	Average Lifespan
Burr plates	Grind turns coarse or uneven; motor runs longer per batch.	2–3 years of daily use (per feedback on old unit).
Glass jar	Hairline cracks or chips near the base.	Replace on visible damage, not on a schedule.
Safety lid	Grinder will not power on even with beans loaded.	Replace as needed.
Power cord	Spotty power drops or fraying near the base.	Replace as needed.

Oily bean residue speeds up physical burr wear. Knowing how to clean a KitchenAid grinder prevents that sticky buildup and extends part life. One PartSelect user noted their original burrs ground nearly 3,000 pounds of coffee over twelve years. That anchor point is huge.

Find Your Exact Model Before Ordering Parts

Check the printed sticker on the bottom base or inside the bean hopper first. Do not guess. Buying parts based only on looks will likely leave you with an annoying return process.

KCG0702CS Burr Grinder — Parts & Part Numbers

The main burr plate assembly goes by part number 4176702 or W10179363. Online stores will sometimes list this exact same internal piece as AP4358269. A single burr costs about $21. Buying a complete two-pack runs roughly $42, though exact checkout prices will fluctuate.

Search for part 4176728 if you happen to break your glass collection jar. Many vendors stock a matching third-party option called KPCGRND. These specific hardware items also fit sibling models like the KCG0702OB and KPCG100 series. A new retail unit costs roughly $350.

BCG111ER Blade Grinder — Parts & Part Numbers

Blade models use completely different hardware components. The main top lid assembly goes by the official part number W10919445. It costs around $24 through repair sites like PartSelect. Because this is a special order item, buyers often face longer shipping delays.

You may also need the metal bowl (BCG1MC) or the standard plastic cover (BCG1PL). A dying safety lid feels terribly loose against the internal switch piece. The normal push-down motion goes soft instead of clicking. Watch for this.

How to Replace Burr Plates on a KitchenAid Grinder (Step-by-Step)

You only need a basic Phillips screwdriver to swap your dull burr plates. Most owners easily finish this simple DIY repair job in under twenty minutes. Follow these basic steps.

1. Unplug the main power cord right away because this is a vital safety step.
2. Empty all whole beans from the top hopper and remove the bottom glass jar.
3. Grab your Phillips screwdriver. Remove the two to four screws holding the top housing lid.
4. Pull the old burr piece straight out and note the washer layout before setting it down.
5. Place the new burr plate inside the housing. Match the old washer setup well.
6. Secure the metal housing back together and lock your clean glass jar to the base.
7. Run a quick test. Grind a tiny batch of beans first to check the output before filling the hopper.

My own burr plate swap took just few minutes to finish. You can test your work easily. A newly installed burr plate turns smoothly by hand with very light effort.

If the metal catches or feels rough, a washer is likely placed wrong inside. Take it apart. Check the exact washer spacing again before you turn on the coffee machine.

Always wipe down the open main chamber. A clean housing stops old coffee oils from ruining your fresh burr plates. This simple cleaning habit adds years to the life of your new part.

OEM vs. Aftermarket Parts — Where to Actually Buy Them

Two paths exist for buying parts. You can order exact OEM pieces through the KitchenAid Owners Center or PartSelect. Amazon sells cheaper third-party items. You simply trade a perfect factory fit for those lower checkout prices online.

	OEM (PartSelect, eReplacementParts)	Aftermarket (Amazon, Walmart)
Cost	Higher ($45.82 for lid)	Often lower (~$21 for burr)
Fit match	Exact fit every time	Mostly fits; some size issues
Stock status	Delays happen on older parts	Often ready to ship now
Warranty	Keeps factory coverage safe	Might void active plans

OEM gear costs more. It fits your machine without any extra hassle. A new factory lid for the blade grinder runs about $46 through official support channels. Third-party burr plates cost just $21, but that cheaper metal sometimes requires slight tweaks.

You might notice Whirlpool part numbers on many store listings. KitchenAid belongs to that parent company. This detail explains why the exact same burr plate shows up under multiple brand labels. They share the same internal factory design.

When a gearbox dies completely, you might find zero parts in stock anywhere. Some buyers turn to appliance forums for used units. They buy a broken grinder just to harvest the working gears inside it. Treat this as a last resort.

Mini Case Study — Fixing Inconsistent Grind After Years of Daily Use

I used my burr grinder every morning for about two full years. I always ground a whole hopper of dark beans right before work. It ran great. The heavy motor never jammed or sounded tired during those daily grinds.

The daily coffee output grew highly coarse over a few short weeks. The main setting dial never moved. My morning drip coffee started brewing much faster than it often should. This fast water flow proved those jagged chunks were ruining the cup flavor.

I knew the heavy motor was still perfectly fine. I finally ordered the factory two-pack burr plate assembly to fix this issue. The exact part number was listed above. I swapped the metal using the simple screwdriver steps I shared earlier.

The machine quickly returned to a highly even and fine output. It worked perfectly. The very first test batch looked totally uniform without any extra dial tweaks. My normal morning brew time finally returned.

Repair or Replace? When New Parts Aren’t Worth It

Buy a completely new grinder if replacement parts cost over a third of the standard retail price. A fresh two-pack of burrs costs just $42, and your DIY labor is free. A brand new KitchenAid KCG0702CS model runs roughly $349.99 today. Fixing the machine yourself wins.

This exact math flips quickly if you break the heavy main motor housing. The main factory also stopped making that specific internal gearbox piece several years ago. Chasing dead parts simply wastes time. Replacing the entire broken unit makes much more sense at that point.

Many shoppers actively compare top kitchen brands like Ninja, Cuisinart, and Breville. A repaired KitchenAid still costs far less than buying matching burr models from those rivals. A simple plate swap serves as a smart one-time hardware refresh. It works perfectly.

You must carefully watch out for repeated hardware failures over a short time span. A second major breakdown means the heavy appliance is nearing the end of its life. This pattern is rarely a fluke. Stop buying KitchenAid coffee grinder replacement parts when multiple pieces fail at once.

FAQ Section

Are KitchenAid coffee grinder parts interchangeable between models? 

Burr plates and glass jars work across the whole KCG0702 and KPCG100 family line. Blade grinder pieces for the BCG111 model do not cross over. They use a totally different cutting setup.

Is the plastic in KitchenAid grinder parts food-safe? 

Factory replacement jars and lids meet standard food-safe ratings perfectly. Official parts stay BPA-free. You must check third-party store listings to verify their exact safety rating before buying.

Does replacing a part yourself void the KitchenAid warranty? 

Self repair causes zero issues after your coverage ends. Using aftermarket parts during an active factory plan might void your warranty. Always read the official terms first.

How long do replacement burr plates typically last? 

Your daily coffee habits change the burr plate lifespan completely. One owner noted their plates processed roughly 3,000 pounds of whole beans. That grinder ran for twelve years.

Can I use a smaller or off-brand burr plate if out of stock? 

You need an exact fit. The wrong size ruins grind evenness and adds heavy strain to the main motor. Search for cross codes like AP4358269, PS970853, or W10179363. Those codes verify a perfect match.

Where should I store spare parts like burr plates or lids? 

Keep your spare parts inside their retail shipping boxes. You must store them in a completely dry cabinet far away from the hot stove. Direct heat cracks thin plastic lids very fast. Be careful.
