Question 1

drip tray is rusting through after one season, is this normal? can i just replace the cheap foil?

Accepted Answer

DIAGNOSIS The stock porcelain-coated drip tray is prone to rust where the coating chips. Acidic drippings accelerate this. FIX Yes, you can and should use heavy-duty aluminum foil on top of the tray. But first, sand the rust off the existing tray with coarse grit sandpaper. Wipe clean. Then cover the entire tray with a single sheet of foil, pressing it smoothly into the curve. Replace this foil after every 2-3 long cooks. IF THAT DIDN'T WORK If the tray is too far gone, order a replacement part. Consider upgrading to a stainless steel aftermarket tray designed for the 700 series—it will last longer. HEADS UP Never let drippings pool and bake on the tray. The carbonized grease is corrosive. Clean or re-foil regularly.

Question 2

auger won't turn at all when i try to prime or start, just a clicking sound from under the hopper

Accepted Answer

DIAGNOSIS The auger motor is seized or jammed solid. The clicking is the internal thermal protector tripping because the motor can't move. FIX Unplug the grill. Empty the hopper. Access the auger system. First, try to manually turn the auger shaft. Find the cleanout cap on the back of the grill, remove it, and use a socket on the exposed auger shaft bolt. Turn clockwise. If it won't budge, you have a severe jam. You must disconnect the auger from the motor (usually a shear pin or set screw) and clear the tube. IF THAT DIDN'T WORK If the auger turns freely by hand but the motor still clicks, the motor is burnt out. You need a new auger motor assembly. Match the part number from your old unit. HEADS UP Never force the auger by running the motor. You will burn it out. Always clear jams manually first.

Question 3

my grill won't connect to the app anymore, it just says searching for device, worked before

Accepted Answer

DIAGNOSIS The Wi-Fi module in the grill has lost its configuration or is stuck. A weak signal during setup is the usual culprit. FIX Perform a hard reset on the grill's Wi-Fi. On the controller, press and hold the 'Wi-Fi' button for 5-7 seconds until the icon blinks rapidly. This clears the old network info. On your phone, forget the 'Z Grills_XXXX' network. Close the app completely. Re-open the app and follow the setup steps again, with your phone very close to the grill. IF THAT DIDN'T WORK Ensure your phone is connecting to your 2.4GHz home network, not 5GHz. The grill module does not support 5GHz. Check your router settings. HEADS UP The grill's Wi-Fi range is very short—about 30 feet with a clear line of sight. Walls and interference will break the connection.

Question 4

how do i clean out the ash from the bottom of my pellet grill, it's piled up under the heat baffle

Accepted Answer

DIAGNOSIS Normal combustion ash accumulation. It must be removed regularly or it smothers the fire and causes temperature problems. FIX Get a shop vacuum. Let the grill cool completely. Remove the grates, heat baffle, and drip tray liner. You now see the interior bottom pan. Vacuum out all loose ash. Pay special attention to the channel around the fire pot. Then, remove the fire pot itself (usually two bolts or screws). Vacuum inside the fire pot and the small hole underneath it where the hot rod is. IF THAT DIDN'T WORK If ash is persistently wet and clumpy, you have a grease leak from the drip tray. Ensure your drip tray liner is properly centered and the drain hole at the front of the grill is clear. HEADS UP Never use a household vacuum. Use a shop vac rated for hot ashes. Embers can linger for over 24 hours.

Question 5

temperature swings are wild on my 700d3, set to 225 but it goes to 300 then drops to 180, not stable at all

Accepted Answer

DIAGNOSIS The controller's P.I.D. settings are off or the RTD probe is dirty. Grease and carbon insulate the probe, giving false readings. FIX Clean the RTD probe thoroughly. Let the grill cool. The probe is on the left interior wall. Scrub it with a brass brush or fine steel wool until the metal is shiny. Do not bend it. Also, vacuum out the fire pot and the entire bottom of the cook chamber. Excess ash causes erratic burns. IF THAT DIDN'T WORK You may need to reset the controller's calibration. For many Z Grills models, you hold the 'Menu' and 'Prime' buttons together for 3 seconds. Consult your specific manual for the 700D3 sequence. This resets the learned temperature parameters. HEADS UP Always let the grill preheat for 15-20 minutes with the lid closed before trusting the temperature reading. Lid-open checks ruin the cycle.

Question 6

z grills fan is crazy loud and sounds like it's rattling, not the normal hum, how do i fix the noise?

Accepted Answer

DIAGNOSIS The combustion fan blade is hitting its housing or a foreign object. A pellet or piece of carbon got past the fire pot screen. FIX Unplug the grill. Remove the cooking grates, heat baffle, and drip tray. Remove the fire pot. Look directly behind the fire pot opening—you'll see the fan housing. Use a flashlight and a long, thin tool like needle-nose pliers. Carefully reach in and remove any debris lodged between the fan blades and the housing. Spin the fan blade by hand to check for clearance. IF THAT DIDN'T WORK The fan motor bearings may be failing. The fan assembly is mounted to the back of the grill. You can access it by removing the rear panel. Replace the entire fan motor assembly if it grinds. HEADS UP Do not operate the grill with a rubbing fan. It can overheat the motor and cause a controller failure.

Question 7

pellet grill starts fine then shuts down after 30 minutes and i get an 'erh' message, keeps happening

Accepted Answer

DIAGNOSIS ERH is a feed error. The auger is failing to deliver pellets to the fire pot at the correct rate, causing the flame to go out. FIX This is almost always a jam in the auger tube. Turn the grill off and unplug it. Empty the pellet hopper completely. Use the supplied cleaning rod or a long, flexible wire. Insert it into the auger intake at the bottom of the hopper. Push firmly to clear any compacted sawdust or broken pellet blocking the auger. You may need to rotate the auger by hand (through the cleanout port at the back) while pushing. IF THAT DIDN'T WORK Check the auger motor itself. Listen when you start a startup cycle—you should hear a distinct humming from the motor under the hopper. If silent, the motor or its wiring has failed. HEADS UP Always use high-quality, dry hardwood pellets. Cheap pellets with excess sawdust or moisture are the main cause of auger jams.

Question 8

my z grills 700d3 just shows 'err' on the controller and won't ignite, what do i do?

Accepted Answer

DIAGNOSIS The controller is throwing a high-temperature error. The RTD probe in the cook chamber is likely reading incorrectly or is disconnected. FIX Unplug the grill. Open the main hopper lid and remove all pellets for safety. Remove the cooking grates and heat baffle to access the rear of the cook chamber. Find the RTD probe—it's a thin metal rod sticking into the chamber from the left side wall. Check its connection. The wire runs to the back of the controller. Ensure that plug is fully seated. Plug the grill back in. If 'err' is gone, reassemble. IF THAT DIDN'T WORK The RTD probe itself may be faulty. You'll need to test it for continuity with a multimeter or replace it. Part number is usually ZPG-7003-0011 or similar for the 700 series. HEADS UP Never bypass or run the grill with an 'err' code. It can cause a dangerous over-fire situation in the fire pot.
