Question 1

i’m trying to use the continuous drain hose on my d50bp but the water still fills the bucket first.

Accepted Answer

DIAGNOSIS The unit is designed to drain through the hose only when the bucket is *in place*. If the bucket is filling, it means the internal diverter isn't activating, usually because the hose setup isn't quite right or there's a blockage. FIX 1) Ensure the bucket is fully inserted and seated. The unit won't divert water to the hose unless it senses the bucket is present. 2) Check your hose. It must be a standard 5/8" ID (inner diameter) vinyl hose, and it must run straight down from the drain port on the back of the unit. There cannot be any loops or kinks, and the entire hose must be on a downward slope away from the dehumidifier. Any uphill section will cause water to back up into the bucket. 3) Make sure the hose is pushed firmly onto the drain nipple and the black rubber grommet is creating a good seal. IF THAT DIDN'T WORK There's a small internal float valve that directs water to the hose port. Sometimes debris or scale can clog the small port. You can try flushing the drain outlet with a little warm water from a cup with the bucket out and the hose off. HEADS UP Gravity drain is key. You cannot pump water uphill with this setup. If your floor drain is higher than the dehumidifier's drain port, you'll need a condensate pump.

Question 2

the fan speed on my friedrich seems weak even on high, and it's not moving much air out the top vent.

Accepted Answer

DIAGNOSIS This is almost certainly a restricted airflow problem. Either the filter is filthy, the coils are clogged with dust, or the fan blade itself is gummed up. FIX Start with the simple stuff. 1) Clean that foam filter as described earlier—let it dry fully before putting it back. 2) With the unit off and unplugged and the filter removed, peek inside with a flashlight. Look at the aluminum evaporator coils. If they're matted with dust or lint, you can gently vacuum them with a soft brush attachment. Be very careful not to bend the delicate fins. 3) While you're in there, see if you can spot the fan blade. If it's accessible, a quick wipe with a damp cloth can remove dust buildup. IF THAT DIDN'T WORK The fan motor itself could be failing. Listen closely—if it's making a grinding or whining noise, the motor bearings might be shot. This requires a parts replacement. HEADS UP When cleaning coils, never use sharp tools or high-pressure air, which can bend the fins and make airflow worse. A soft brush and a vacuum are your best friends here.

Question 3

water is leaking from the bottom of my d50bp, not from the bucket overflow. it's pooling under the unit.

Accepted Answer

DIAGNOSIS This points to an internal drain pan leak or a clog in the internal drain system if you're using the continuous drain hose. The water is finding a way out of the chassis instead of into the bucket or hose. FIX 1) Turn it off, unplug it, and empty the bucket. 2) Move the unit to a dry area and tilt it slightly back to see if water drips from a specific spot. 3) Check the continuous drain hose connection on the back. Make sure the rubber grommet is seated correctly and the hose is pushed in all the way and not cracked. If you're not using the hose, ensure the drain port plug is firmly in place. 4) Inspect the bottom of the bucket for cracks, especially around the handle area. IF THAT DIDN'T WORK The leak could be from the internal drain pan, which is a plastic tray that catches condensation before it routes to the bucket. This can crack or become disconnected. Diagnosing this requires opening the cabinet, which is a job for a qualified technician. HEADS UP Don't let it keep running with a leak. Water near electrical components is a hazard and can cause more damage to the unit and your floor.

Question 4

the friedrich dehumidifier won't turn on at all, no lights, nothing. i checked the outlet and it's good.

Accepted Answer

DIAGNOSIS With no power lights at all, we're looking at an internal fuse, a failed control board, or a problem with the power cord connection inside the unit. FIX First, double-check that the outlet is live by plugging in a lamp or phone charger. If that's good, locate the reset button. On many Friedrich models, there's a small, red reset button on the plug itself or on the lower back of the unit. Press that firmly. Then, try a different outlet if possible, making sure you're not using an extension cord, which can sometimes cause issues. IF THAT DIDN'T WORK There's an internal thermal fuse on the control board that can blow. This isn't a user-serviceable part for most folks. Your next step is to contact Friedrich customer service—they can often talk you through a simple check or set up a repair. HEADS UP If you smell anything electrical or burnt near the unit, do not keep trying to reset it. Unplug it immediately and call for service, as there could be a more serious internal fault.

Question 5

how do you clean the friedrich d50bp filter? can i just rinse it or do i need to buy a new one?

Accepted Answer

DIAGNOSIS You're right to clean it—a dirty filter is the number one cause of reduced airflow, inefficiency, and coil freeze-up. The filter is reusable and meant to be cleaned. FIX 1) Power off and unplug the unit. 2) The front grille should pull off—grip it at the bottom and gently pull it forward. 3) The rectangular foam filter slides out. 4) Take it to a sink and rinse it thoroughly under lukewarm water. Don't use soap or harsh chemicals, as the residue can get pulled into the system. 5) Gently squeeze out the excess water (don't wring it) and let it air dry completely before reinstalling. This can take 24 hours. IF THAT DIDN'T WORK If the filter is torn, heavily degraded, or still seems clogged after rinsing, you can order a replacement directly from Friedrich. The part number is usually on the filter frame itself. HEADS UP Never run the dehumidifier without the filter. You'll let dust and hair coat the evaporator coil, which kills efficiency and can lead to much bigger problems.

Question 6

my d50bp is making a loud gurgling or bubbling noise from inside, is that normal?

Accepted Answer

DIAGNOSIS That's usually the sound of refrigerant flowing through the coils, especially right after startup or during a defrost cycle. It's often normal, but if it's a new, very loud sound, it can indicate the unit is tilted. FIX First, check that the dehumidifier is sitting perfectly level on a firm floor. Use a small level or just eyeball it front-to-back and side-to-side. If it's leaning even a little, the refrigerant and condensed water might not be draining correctly through the internal lines, causing noisy flow. Adjust the feet if yours has them, or shim it gently with a thin piece of cardboard under the low side. IF THAT DIDN'T WORK If the noise is more of a loud knocking or rattling, it could be a loose compressor or fan assembly. With the unit off and unplugged, you can gently press on the side panels to see if it changes the noise when you restart it. If so, the cabinet might need tightening. HEADS UP A constant, hissing sound is different and not normal—that could indicate a refrigerant leak. In that case, shut it off and call for service.

Question 7

friedrich d50bp fan is running but it’s not pulling any water out of the air, humidity isn't dropping

Accepted Answer

DIAGNOSIS The compressor likely isn't kicking on. This can be a refrigerant issue, but more commonly it's a clogged or frozen evaporator coil preventing the cooling cycle. FIX 1) Turn the unit off and unplug it. 2) Open the front grille (it usually just snaps off). 3) Look at the cold coils behind the filter. If you see a solid block of ice, that's your problem. 4) Let it thaw completely—this can take many hours. A fan pointed at it can help. 5) Before restarting, check that your air filter is clean and that you're not running it in a very cold room (below 65°F). Low temps can cause it to freeze up again. IF THAT DIDN'T WORK If the coils were clear and it's in a warm enough room, the issue might be low refrigerant, which isn't a user-serviceable fix. You'd need to contact Friedrich support. HEADS UP Running it continuously in a damp, cool basement is a classic way to cause coil freeze-up. Consider using the built-in humidistat to cycle it on and off, or get a separate timer to give it regular breaks.

Question 8

my friedrich d50bp dehumidifier just keeps showing the bucket full light even though i emptied it, what’s going on?

Accepted Answer

DIAGNOSIS This is almost always a misaligned or stuck float switch in the bucket compartment. The little plastic tab that senses when the bucket is full isn't dropping back down. FIX First, power the unit off and unplug it. Pull the bucket all the way out. Look inside the empty compartment on the left side—you'll see a small, usually white, plastic float. Gently press it up and down with your finger a few times. You should feel it click smoothly. Sometimes it just gets hung up. Then, reinsert the bucket carefully, making sure it slides all the way in without hitting that float. Plug it back in and power on. IF THAT DIDN'T WORK Check the bucket itself. Make sure it's seated perfectly flat on the floor and that the little notch on the front is clicking into the unit's base. If it's even slightly crooked, it can hold the internal float up. HEADS UP Never try to run it with the bucket removed to bypass this. You'll flood your floor. The safety switch is there for a reason.
