MODEL OVERVIEW
About this model: GE PDT846SMJES
Hidden-control slate dishwasher with a confirmed Floor Protect with Alert leak message.
Recognize this particular Profile model
PDT846SMJES is a GE Profile dishwasher with controls hidden on the door's upper edge. Its exact GE listing names an LCD control display, a cycle-status bar on the door and a fingerprint-resistant slate exterior. GE rates this configuration for sixteen place settings. Those details identify the unit more reliably than a family-manual drawing, because the linked booklet illustrates neighboring PDT845 and PDT855 panels without separately labeling PDT846.
The product listing gives PDT846SMJES seven cycles, Power Dry with Fan Assist Dry and a 42 dBA quiet package. This mix of a relatively quiet wash and a door status display explains why a visible light can matter when the controls are concealed. It does not make every sound or every illuminated word an error. Use the exact model number before borrowing a control sequence from another Profile dishwasher.
Read the leak alert accurately
GE explicitly specifies Floor Protect with Alert for PDT846SMJES. GE's support explanation says that this named feature uses a moisture sensor in a pan below the dishwasher and displays LEAK DETECTED when it finds moisture. The linked owner manual calls leak protection a feature on some models; its page 6 says an equipped dishwasher stops its cycle and drains, and page 22 maps the message to a possible leak requiring service. The exact feature specification resolves that family-manual qualification for this model.
If LEAK DETECTED appears, note the literal wording and contact GE service as the manual directs. The displayed warning does not identify which seal, hose or internal part failed, so a component diagnosis would go beyond the evidence. A door left open during a wash creates a different condition: the manual describes a minute-by-minute reminder beep and says to press Start and close the door within four seconds to resume. Record that symptom separately from a leak alert.
Choose a cycle and load for it
The exact product page lists seven programs. In the family manual, AutoSense responds to soil level, Heavy addresses baked-on cookware, Normal is the everyday energy-rated choice and Light suits lighter loads. Rinse holds a partial load without detergent; Express is a shorter wash for lightly soiled dishes; eWash emphasizes low water and energy use. GE warns that actual time changes with soil, inlet temperature and selected options, so a changing countdown alone is not a leak code.
For a smaller load, PDT846SMJES lists upper-only and lower-only Wash Zone choices, allowing a single rack to be targeted. The same exact specification includes Bottle Jets for narrow containers. These options address wash coverage; they do not change what LEAK DETECTED means. GE's sixteen-place-setting rating describes capacity under ordinary loading, while tall items still need clearance around the detergent cup and spray arms. If cleaning is poor, consider the rack arrangement before assuming a sensor fault.
Separate drying and status from faults
GE lists both Power Dry and Fan Assist Dry for this model. The manual explains that, with the hidden-heater arrangement, the drying fan may run as long as ninety minutes after a completed wash and stops if the door is opened. Incoming water should be roughly 120 to 150 degrees Fahrenheit, and rinse aid can help reduce spots and wet plastic. Those conditions help explain damp dishes or post-cycle airflow; none is a substitute for service when the actual leak message appears.
The exact control specification includes separate Clean, Sanitized and Low Rinse Aid lights. The manual makes their meanings narrower than a generic fault indicator: Clean marks completion, Sanitized depends on achieving the required heating conditions and Low Rinse Aid points to the dispenser supply. Start and a fully closed door are needed to begin or resume a wash. Reading these ordinary cues first can prevent a paused cycle or empty rinse-aid dispenser from being mistaken for the Floor Protect warning.
Care for the slate version and describe other symptoms
The SMJES finish matters for care. GE calls the exterior fingerprint-resistant slate, and the linked manual identifies an ES suffix as a slate painted door panel. For that panel it recommends a clean, soft, lightly damp cloth followed by drying, rather than the stainless-steel cleaner directions printed beside it. The same manual recommends checking its fine and ultra-fine filters about every other month, sooner if dishes feel gritty or washing declines. These are maintenance steps, not a reset for LEAK DETECTED.
When the controls respond but water never enters, the troubleshooting table separately mentions the door latch, the supply valve and a stuck flood float. When standing water fails to pump out, it points to an air gap, disposer or kitchen-sink drain. Neither symptom proves the under-unit Floor Protect sensor has tripped. Give service the exact message or symptom you observe: a literal LEAK DETECTED warning calls for the service route on page 22, while no-fill and no-drain problems have their own checks.
