Everyone out first. Food at risk? Move it Water near power in a working kitchen is a same-day problem. People clear, breaker off from a dry panel, supply valve closed if safe, then book. The machine stays off until the leak is found and the wiring near it is checked. ## What it usually means. Most commercial kitchens are built to get wet, with floor drains, sloped tile and equipment on legs. The danger is where water meets power: extension cords behind prep tables, receptacles low on the wall, plugs for reach-ins and a dish machine wired close to its own drain. That is why the first step is keeping people clear and cutting the power at the breaker, from a panel that is dry and can be reached without standing in water. Only then is the source looked for. The usual ones are easy to list. A reach-in's condensate pan overflows when its evaporator ices up and then thaws. A walk-in's drain line freezes or clogs and the defrost water lands on the box floor and runs out under the door. A dish machine leaks at its door gasket, its drain hose or its fill line. A combi's drain packs with scale and grease. In a laundry, an extractor's drain valve sticks and the water goes over the edge. A floor drain backing up from the grease trap sends water up instead of down, and that is a plumbing job the visit points out rather than repairs. The 6 causes, cheapest first Answer these first 01 Where is the water deepest: under the dish machine, at the walk-in door, below a reach-in or behind the cooking line? 02 Are any cords, plugs or outlets touching the water or close to it? 03 Is the water clear, soapy, greasy, or does it carry food scraps from a drain? 04 Does it grow while one machine runs and stop when that machine stops? 05 Is a floor drain nearby standing full or pushing water up? ## Check these before you book. Water on commercial kitchen floor: 5 checks, and none of them costs anything. 01 Keep staff and customers away from the water, and put out wet-floor signs. 02 Turn off the affected equipment's breaker from a dry panel; if reaching the panel means standing in water, do not do it and book the visit. 03 Close the water supply valve to the leaking machine if it is dry and easy to reach. ### Also worth checking - Photograph where the water begins and note which machine was running when it appeared. - Never touch plugs or cords lying in water, and never open a panel on wet equipment. ## The causes, cheapest first. 6 things water on the commercial kitchen floor near equipment and outlets turns out to be, from standing water left after the nightly hose-down to extractor drain valve stuck in a laundry. [The cost guide](https://commercialappliancerepair.center/cost/) 1. 01 no repair ### Standing water left after the nightly hose-down Closing crews rinse the floor and push water toward a drain that cannot take it all at once. It clears on its own, but squeegee it away from cords and plugs before the morning shift arrives. No repair: check it yourself 2. 02 low ### Reach-in condensate pan overflowing A pan under the cabinet catches defrost water and evaporates it with a heater or hot gas; when that heater fails, the pan spills onto the floor. The heater and the drain tube are replaced on a visit.

The line is cleared, and its heater tape is replaced where the drain passes through a freezer.

The leak is traced with the machine running and its panels in place, then the worn part is changed.

The drain is cleared and the steam generator inspected.

The valve is cleared or replaced with the machine powered down.

Is that a repair for you or a plumber? A drain backing up from the grease trap or the building line is plumbing. The visit tells which side it is on; if the machine itself is fine, you get a clear note for the plumber. ### Is it safe to mop around a reach-in that is still plugged in? Only if the cord and outlet are dry and well above the water. If the plug sits in the puddle, switch the breaker off from a dry panel first. ### Why does water pool at the walk-in door every morning? Most often a defrost drain line that freezes or clogs overnight. The water reaches the box floor and runs out under the door. ### Can we keep using the dish machine with a small leak until Monday? A drip away from any power can wait for the booked slot if the floor is kept dry. A leak that reaches cords or outlets means the machine stays off. --- **[Read on the site: Water on the Commercial Kitchen Floor Near Equipment and Outlets: Causes and Fixes](https://commercialappliancerepair.center/problems/commercial-water-on-the-floor/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
