Do you see water? Is the water supply connected correctly? Is the float switch connected? Does the drip tray need to be emptied? Are there excessive suds? Dishwasher was Professionally Installed – F8E4 Error Code If you are receiving the F8E4 error code and the dishwasher was recently installed, check the following: If you see water in the drip tray, it must be emptied. To remove the drip pan assembly, press the snap at each side of the plastic tray in toward the center of the product and pull toward yourself. Take caution not to pull too far or too hard as the float switch wire is still connected at this time and pulling too far or hard can damage the wire. To remove the code: Dishwashing detergent does not create suds, but dish soap does. If suds, bubbles, or soap foam are present when you open your dishwasher, turn off the dishwasher and allow suds to dissipate. Using the wrong type or too much detergent can cause over-sudsing. The suds may push water out of the dishwasher, causing leaking or poor wash performance. Use only detergent specifically designed for automatic dishwashers. Dishwashers should be cleaned approximately every 30 days for optimal performance. Using affresh® Dishwasher Cleaner every month will help keep your dishwasher from filming and spotting and keep the interior clean and free of odors. The drain sequence will begin, and machine operation will be prevented. Those are the maker’s words, taken off its own support page for this condition on a dishwasher. We have not improved them and we have not paraphrased them into something that sounds more certain. Everything below this line is ours, and it is written from what this equipment does in a Miami kitchen rather than in a manual. ### F8E4 is two numbers, not one It is **F8** followed by **E4**, and they answer different questions. The F says which function noticed; the E says what it noticed. That is why F8E4 sits beside F8E0 and nowhere near F1E1, which on a small display looks almost identical and has nothing to do with it. Copy both halves down before you clear anything. Counted across every condition in this archive, the F8 group points at the **cooling fan and airflow** more than at anything else: 8 of the 9 F8 conditions that carry a published meaning. JennAir states no such rule anywhere — this is simply what its own pages add up to when you total them, and we recompute it every time this archive is rebuilt so it cannot quietly go stale. Everything else published under F8 for the dishwasher: [F8E2](https://jennairmiami.support/error-codes/error-code-f8e2-dishwasher/), [F8E5](https://jennairmiami.support/error-codes/error-code-f8e5-dishwasher/). Worth knowing because a display that has shown two of these in a week is describing one problem twice rather than two problems once. ### Try this before you book anything What follows is JennAir’s own list for F8E4 on a dishwasher, not ours, and it is worth the five minutes it takes. A fair number of these end the whole thing at no cost, which is the reason this archive is here to be read rather than behind a booking form. - Remove the Code - Check all the connection points. Be sure the rubber washer is properly seated in the fitting for any connection point. Slide the 3/4" (19 mm) fitting of the 90° elbow up to the valve and hand-tighten it to avoid cross-threading. Hand-tighten until the coupling is tight. Using pliers, check the tightness of the coupling. An additional 1/4 to 1/2 turn may be required to seal the rubber gasket. Make sure to route the fill hose out the rear left side of the unit. - Ensure the float switch is properly connected. Also, ensure that the power supply wire or cord does not touch the dishwasher motor or the lower part of the dishwasher tub. Reconnect the float switch by aligning the connector with the connector housing and pushing in until the locking tab is visible over the back of the connector. - Press the Cancel key once to silence the alarm tone. - Press the Cancel key again to clear the code. - Turn off the water supply to the unit. - Press the Cancel key once to silence the alarm tone. DO NOT turn off the power and keep the door closed. ### Where to go from here The same number is published for the [wall oven](https://jennairmiami.support/error-codes/error-code-f8e4-oven/) as well, and it means something different on each of them. Go to the page for the machine in front of you rather than the one that came up first — which is exactly why no title in this archive is a bare number. And one thing this archive says on every page rather than burying: **the number is not this badge’s property.** JennAir runs the same control platform as the other names in its corporate group, and the page for F8E4 sits at the same address under more than one of them. Far from awkward, that is the most useful fact here: **the code names the subsystem and the model number names the machine.** Which makes the plate inside your door frame half of every answer on this site. Every other condition is in the [JennAir code archive](https://jennairmiami.support/error-codes/), searchable by number. Send us the model number and the display exactly as it reads and you will hear what it points at before anything is booked. We are independent and we work across Miami-Dade, Broward and Palm Beach.
