A Few Last Things I've Learned the Hard Way
Look, if you're managing a restaurant, a shared kitchen, or even a large-scale office pantry setup, you know the deal. Equipment doesn't break on a schedule. It breaks on a Friday night, right before a big event, or when the health inspector is due. I've been on the other end of those frantic calls for years now – the person who gets the 3am text about a washer that won't drain or a freezer that's become a block of ice.
This isn't a long-winded theory piece. This is the four-step checklist I use when I'm triaging a facility's appliance issues. It's the framework we use to prevent the most common (and most expensive) commercial kitchen failures. If you follow these steps, you'll spend less time in emergency mode and more time running your operation.
Step 1: Master the Machine's Language (Error Codes & Alerts)
I still kick myself for the first year of my career when I ignored the blinking lights. A client called about a UE on LG washer – an error I'd seen a dozen times but never really understood. I sent a technician out, he spent two hours, and the fix was something I could have coached them through over the phone in five minutes. The 'UE' error on an LG washer typically stands for 'Unbalance Error' or 'Unbalance Exception.' The machine detects that the load is uneven, preventing the high-speed spin to protect the unit.
Here's the actionable checklist for this step:
- Document the code: When an error appears, don't just clear it. Write it down. Take a photo. The specific code matters. A 'UE' is different from an 'OE' (drain error) or an 'LE' (motor lock).
- Check the source: Nine times out of ten, a 'UE' error is a user-side problem. The load is too large, too small, or tangled (common with bulky items like comforters or mats). LG's ThinQ platform (like on the LG ThinQ dishwasher) is actually useful here – it often provides a more detailed diagnosis in the app than the panel display.
- Know the reset sequence: For most LG washers, a simple power cycle (unplug for 60 seconds) won't always clear a persistent error. The proper sequence is often: Cancel/Off button, then select a new cycle. For the dishwasher, it might involve holding down two buttons (like Delay Start and Energy Saver) for three seconds. Get this memo into your maintenance binder.
Step 2: Plan Your Freezer Wars (The 'How to Organise Chest Freezer' Principle)
During our busiest season last year, I got a call from a catering company. They'd lost $2,000 in product because their chest freezer had become an inefficient, frozen-solid mess. The compressor was running constantly, and they couldn't find the frozen stock they needed. The problem wasn't the hardware; it was the chaos inside. Knowing how to organise chest freezer space is a critical operational skill, not just a domestic chore.
The goal isn't just neatness – it's airflow, temperature stability, and inventory management.
Your breakdown for this step:
- Zones, not piles: Use heavy-duty, clear plastic bins. Designate zones: one for proteins, one for prepped vegetables, one for frozen stock, one for 'use first' items. Never, ever just toss bags in. (Honestly, I'm not sure why some professional kitchens still do this. My best guess is that it's 'faster' in the moment, but it creates a cascade of problems.)
- Airflow is king: Leave a 2-inch gap around the walls of the chest freezer. Don't line the walls with deep-frozen bags. The machine cools most efficiently when air can circulate. Overfilling can cause the compressor to run longer, leading to a surprise utility bill.
- The FIFO rule: First In, First Out. This sounds basic, but it's the first thing to break under pressure. Use a marker on the bins. When you put new stock in, your old (but still good) stock goes on top or in front.
Step 3: Don't Let 'Average' Kill You (Dimensions, Clearance, & Access)
I knew I should have measured the space before signing off on a new refrigerator order, but thought 'what are the odds?' Well, the odds caught up with me when the delivery team couldn't get the unit through the doorway. It cost us $400 in return fees and a furious client. Knowing the average dishwasher width is just the start. It's the clearance, the installation path, and the service access that matter.
This step is about the physical reality of the kitchen:
- Standard vs. Reality: The standard average dishwasher width is 24 inches (61 cm). That's for undercounter models. But a commercial undercounter unit might be 24.5 inches. A built-in oven is usually 30 inches. Use a tape measure, don't trust a spec sheet. Check the depth, too – the standard is 24-25 inches, but some models with a larger heating element or soundproofing are deeper.
- The 3-Door Rule: Can the appliance fit through the door of the room? Can it get around the corner? We had a client who bought a brand-new, massive refrigerator that could fit through a 36-inch doorway—but their kitchen door was 32 inches. That was a $5,000 mistake.
- Service Access: An appliance needs air. A built-in refrigerator or a washer/dryer stack needs at least a small gap for ventilation. If you shove it flush against the wall, you're guaranteeing overheating and premature failure. Check the manual for specific clearance requirements (i.e., 1-2 inches on the sides, more at the back).
Step 4: The Stupid Filter (The Details That Kill You)
Skipped a final review of the water filter schedule because it 'never matters.' That was the one time it mattered. A client's entire ice machine started producing cloudy, foul-tasting ice. The culprit? A clogged water filter. They were using a standard filter, but the local water supply had changed, and the filter couldn't handle the sediment load. I even had a client ask if they could use electric shaver cleaning spray to clean the filter intake (please, please don't. That's a fire and health hazard).
This is the step everyone forgets until it's a crisis:
- Create a filter map: Most commercial kitchens have multiple filter points. The water line for the coffee machine. The ice maker. The refrigerator's water dispenser. The dishwasher's intake filter. Create a document with the model numbers and the recommended replacement schedule (e.g., 'Every 3 months for the LG refrigerator filter, every 6 for the coffee machine').
- Don't 'Delay Replace': Clogged filters restrict water flow, which causes appliances to work harder (pumps, valves, compressors). This leads to more error codes, more service calls, and higher energy bills. Think of it this way: a $50 filter every six months is cheaper than a $250 service call.
- Use the right tool: Don't use a non-standard filter. An off-brand filter might not fit correctly, causing a leak. For LG refrigerators with the ThinQ water filter, the system actually tracks the filter's life. If you ignore it, it'll start beeping at you. Listen to the beep.
A Few Last Things I've Learned the Hard Way
One of my biggest regrets: not investing in a simple, shared logbook for equipment maintenance earlier. The goodwill I'm working with now took three years to develop, and it started with admitting when the logbook was blank. Don't try to remember everything. Write it down. The 'UE error' you saw last month? If you didn't log it, it never happened.
There's something satisfying about a kitchen that hums along without drama. After all the frantic calls and the '2 hours until service' panic, seeing a well-organized, correctly-maintained facility is the payoff. It's not about the fancy tech; it's about the simple, boring checklists. The ones on this page, for instance.
