Are Pit Boss Grills Waterproof? | Rain-Ready Use Rules

Pit Boss grills handle a brief shower, but they aren’t sealed—keep the controller, hopper, and pellets dry with a fitted cover.

Pellet grills are outdoor machines. They’re built for patios, decks, and backyards. Still, “outdoor” doesn’t mean “waterproof,” and rain is the fastest way to turn a smooth cook into a jammed auger or a finicky controller.

This guide breaks down what water can reach on a Pit Boss, what usually stays fine, and what to protect each time.

What “Waterproof” Would Mean On A Pellet Grill

Waterproof would mean sealed electronics, gasketed doors, and a published water-ingress rating. Most backyard pellet grills don’t claim that. They’re made to live outside with routine protection: smart placement, dry pellets, and a cover once the grill is cool.

Are Pit Boss Grills Waterproof? (Straight Answer With Real-World Detail)

No. Pit Boss grills are not waterproof units. Light moisture on the body is normal. The trouble spots are the controller, the hopper area, and anywhere pellets can absorb water.

Many people cook through a short sprinkle with no issues. Long rain, wind-driven rain, or water pooling near seams is where headaches start.

Parts That Usually Handle A Little Rain

• Lid, barrel, cart frame: Painted steel can get wet and dry out without damage when it’s kept clean.
• Chimney and cap: Rain streaks are common. Wipe them off when dry.
• Cooking grates and heat plates: These can rust if they stay damp, so keep them brushed and lightly oiled after cleaning.

The big rule: water that sits for days causes far more wear than a quick wetting that dries fast.

Parts That Don’t Like Getting Wet

Controller And Display

The control panel has buttons, a screen, wiring, and connectors right behind the faceplate. Repeated wetting can lead to corrosion, display fogging, or failure.

Pellet Hopper And Pellets

Pellets soak up moisture, swell, crumble into dust, then harden. That can jam the auger and create uneven feeding.

Seams And Openings

Water can creep in around hopper lids, rear seams, grease drain paths, and fan intake areas. Wind pushes rain into gaps that stay dry on calm days.

Cooking In Light Rain Without Wrecking The Grill

If you’re tempted to cook with clouds overhead, keep it simple and cautious.

Pick The Right Day

• Okay: Light mist, short sprinkle, calm conditions.
• Skip it: Storms, strong wind, sideways rain, or any weather that can soak the controller and hopper.

Set The Grill To Drain Away From The Hopper

If your patio slopes, put the hopper side on the higher edge so water won’t sit along the hopper lid seam. Also keep the grease bucket where rainwater can’t splash into it.

Keep The Controller Out Of Direct Rain

If rain starts mid-cook, keep the lid closed so temps stay steady. Then block water hitting the controller and hopper lid. A patio umbrella or a small rigid shield works, as long as it stays clear of the chimney and any hot surfaces.

Cover Only After Cool-Down

Let the grill cool, wipe off puddles, then cover it. Don’t trap heat under fabric.

Cover Choice And Outdoor Storage Habits

If your grill lives outside, a fitted cover is the easiest protection. Pit Boss sells model-specific covers in its Pit Boss cover lineup.

A good cover fits low on the cart, doesn’t flap in wind, and sheds rain without pooling. If your cover sits loose, tighten it with built-in straps or add a bungee at the bottom edge.

One more habit pays off fast: park the grill under a roof edge, awning, or porch when you can. Less direct rain means drier seams and longer paint life.

Avoid Loose Tarps And Plastic Wraps

A cheap tarp feels like protection, yet it often funnels water into the cart and holds damp air against the body. If you use a tarp in a pinch, leave gaps at the bottom so air can move, and remove it once the weather clears. A fitted cover that sheds water is a better long-term move.

Watch For Condensation Under The Cover

Even on dry days, temperature swings can leave water droplets under a cover. You’ll notice it as a damp controller face or a musty smell when you lift the cover. A quick fix: prop the cover open for 15–20 minutes on a dry afternoon, then close it back up once the grill feels dry.

Pellets And Moisture: Keep Fuel Dry Or Expect Trouble

Even if the grill body looks fine, damp pellets can ruin your next cook. In humid or rainy weeks, pellets can soften in the hopper overnight and feed poorly.

If you won’t cook for a few days and rain is likely, empty the hopper into an airtight container and store it indoors. If pellets already feel soft, clumpy, or swollen, don’t run them “to use them up.” Dump them and start fresh.

Signs Pellets Picked Up Moisture

• Pellets look dull and feel soft when you pinch them.
• A lot more sawdust collects at the bottom of the hopper.
• The grill struggles to climb to temperature, then swings up and down.
• You hear a squeal or grinding sound as the auger turns.

If you catch those signs early, clearing the hopper and refilling with dry pellets can prevent a full auger jam.

Water Exposure Risk Map For A Pit Boss Pellet Grill

Area	What Water Can Cause	What To Do
Controller face and buttons	Moisture behind panel, corrosion, shorting	Store under cover; shield during surprise showers
Hopper lid seam	Pellets absorb moisture, swell, jam auger	Use fitted cover; keep hopper on higher side if patio slopes
Pellets in hopper	Clumps, dust, uneven feeding	Empty hopper before multi-day rain; store pellets in sealed bin
Auger tube	Pellet paste hardens, binds auger	Remove damp pellets early; vacuum dust often
Fan and intake openings	Moist air and drips reach wiring	Avoid windy rain cooks; keep grill covered when idle
Grease drain and bucket	Water mixes with grease, overflow, mess	Empty bucket; keep drain path clear after storms
Barrel bottom and ash zone	Wet ash clumps, rust starts faster	Vacuum ash only when cold; air out the grill on dry days
Cooking grates	Surface rust	Brush dry; wipe with thin cooking oil film

Rust Control When Your Grill Stays Outside

Rain isn’t the only culprit. A cover that traps moisture can keep the grill damp for days. That slow-dry cycle is what speeds up rust.

Let The Grill Breathe After Big Rain

On the next dry day, lift the cover for a bit so moisture can escape. If you see pooled water on top of the cover, dump it off so it doesn’t drip down the same seams all week.

Keep Grease From Holding Water

Grease collects moisture and grime. Scrape the drip tray and clear the grease channel on a schedule you can keep. A clean drain path also stops rainwater from backing up into the barrel.

Handle Paint Chips Early

If you spot bare metal, touch it up with a high-heat paint that matches your grill’s spec. Bare steel plus repeated wetting is where rust gets started.

Power And Plug Setup In Wet Weather

Pellet grills need electricity for the igniter, fan, and controller. Keep the power side dry and off the ground.

• Use an outdoor-rated, GFCI-protected outlet when possible.
• Keep cord connections lifted so they can’t sit in puddles.
• Unplug the grill after it cools, especially before storms.

Pit Boss outlines warranty scope and exclusions in its warranty policy. If you’re dealing with a controller issue after rough weather, expect care and storage to matter.

What To Do If Your Pit Boss Got Soaked

If a storm caught you off guard, act fast so wet pellets don’t harden and moisture doesn’t sit in the controller area.

Shut Down And Unplug Safely

If the grill is running and it’s safe, finish the shutdown cycle. If water is pouring onto the controller, turn it off and unplug at the outlet with dry hands.

Check The Hopper First

Open the hopper and feel the pellets. If they’re soft, swollen, or clumped, remove them right away. Once the grill is cold, vacuum out dust and crumbs.

Dry The Controller Side

Wipe the panel and seams with a dry cloth. Then leave the controller side open to air in a dry spot so air can move across it.

Clear Wet Ash And Grease Water

Wet ash cakes up. After full cool-down, vacuum the burn pot area and barrel floor. Dump any rainwater that collected in the grease bucket.

After-Rain Recovery Timeline

Time Window	What To Check	What To Do
Right away	Controller getting soaked	Shield panel; shut down; unplug
Within 30 minutes	Hopper pellets	Remove swollen pellets before they harden
Same day	Grease drain and bucket	Dump water/grease mix; clear drain path
After full cool-down	Ash and burn pot	Vacuum ash; wipe barrel dry
Next cook	Auger feed and ignition	Refill with dry pellets; watch for smooth feed
Next 7 days	Rust spots on grates and seams	Brush rust; wipe with thin oil film

Long Break Storage In Wet Seasons

If you’re parking the grill for weeks, treat it like you’re putting food gear away, not patio furniture.

• Empty the hopper and remove pellets from the auger path.
• Vacuum ash after the grill is cold.
• Clean grease so it can’t trap moisture.
• Cover the grill, then keep water from pooling on top of the cover.

Simple Checklist For A Rain-Safe Routine

• Cover only after the grill is cool and dry on the outside.
• Keep pellets indoors in sealed containers when rain is likely.
• Unplug after cooks and keep plugs off the ground.
• Air out the grill after big storms so moisture doesn’t linger.
