Question about Comfort-Aire BHD-501 Dehumidifier

1 Answer

Tank full light flashes & unit will not operate, but is attached to a hose

I removed the overflow switch and took it to be tested. It was not defective. I replaced it and waited a few days and the dehumidifier worked for about 12 hours and is now not working. The repairman where I took the switch said there was another problem, not the switch. I feel the switch might be erratic. Thanks for your help.

Fill light on and beeps but holding tank is empty


If it is like mine, the plastic part attached to the float in the collection bucket is broken and no longer actuates the switch that indicates the collection bucket (holding tank) is full. When I checked several years ago, the replacement part was no longer available. I used tape to keep the switch in the position that allowed the dehumidifier to operate and attached the hose connector to allow the condensate to drain. The collection bucket isn't needed anymore with this arrangement.

See previous answer. If new, contact supplier to replace float switch. Are you sure it's not just a fan staying on with the tank out?

Our bucket full light is on but we only have a hose running out to the drain. My husband shorted out that circuit but the light still comes on and we can't turn on the unit. Any help with this? Thanks


The reason the light cam of the first time was because the either the attached hose is clogged or the hose connection of the unit is clogged. When this happens, the bucket full light comes ON, because of the clog or the bucket was not reinstalled properly and didn't trip the bucket, safety removal, trigger switch. Be sure the bucket is reinstalled so the the Top and Bottom fit squarely into the bucket holder.

Hopefully, your husband can undo what he's already done, clear the clogs and the unit may run again, as it should.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

We had a hose attached to empty into a drain, but the hose came loose. Now it won't run because it shows the bucket is full.


Was the hose attached to the bucket or directly attached to the inside of the humidifier?
If it was to the bucket, the hose may have slightly pulled the bucket out of place, disengaging the safety switch. Unplug the unit and wait 5 minutes. Then plug the unit back in. Turn it to ON and remove the bucket and carefully reinstall it. You should hear a "click" sound when it's properly in place and the unit should start back up,

Hope this helps to solve your problem.

Attached a pump to drain collected water. The


the water should still collect into the tank. the dehumidifier had a float switch that shut the unit off when the tank is full. In turn it should have a second switch, probably a float switch that turns the pump on and off so that the pump doesnt continue to run when there is no moisture in the tank

FULL LIGHT FLASHES


An automatic overflow switch and Container “Full” indicator light are provided to turn the
dehumidifier off before the container overflows. When the indicator light on the control panel
glows, the water container must be emptied. If the light remains on and the dehumidifier does
not begin to operate make sure the float is attached to the water container.


When the condensate water container is full, the indicator lights up.
1. Turn the power off before removing container. Wait 3 minutes for
any remaining water to drain into the condensate container.
2. Tilt the container forward then lift carefully by the handle.
3. Empty and gently re-insert the container.
Important:This water is not suitable for drinking.

Please rate and god bless:)

Internal pum hose connection?


I just fixed the same problem on my DE-500P. The pump filter was blocked and there was a layer of scummy lint-like stuff in the bottom of the pump reservoir (not the main - or overflow tank) also blocking flow down through the filter to the pump. Repair steps are as follows:

1. Remove the overflow water tank and the two side covers (five screws in each). Note that as you go through the removal of all the covers and other procedures, there are two lengths of screws; don't switch them. If you lose track, the rule of thumb is use the short screws for going through a single layer of plastic into metal.

2. Remove the rear cover (take out the screws along the bottom and on the sides). It will still be attached to the front top cover at the top with tab fasteners. Gently pull out the bottom of the cover while depressing the top of it on both sides with your thumbs (about an inch and a half inside the trim ridges) to clear the tabs. Ease the top part of the cover back and remove it (it will have to tilt to one side, don't forget this when putting it back on).

3. Remove the top cover, not forgetting the two screws on top by where the back cover attached (go gently, there's a wiring harness) and turn it to the side. There was enough slack to leave the wires connected; just be careful to not damage them.

4. The filter looks like a small transparent in-line gas filter. Remove the pump filter, leaving the short tube attached to the top of it. I quickly atttached a length of tubing to drain the reservoir into a bucket. I couldn't find a replacement filter, so I filed a slot in the side of the bottom half of it to remove the gunk using the wire from a twist tie (the upper half had some tabs inside that would have been in the way). Afterwards, I wrapped it tightly with stretchy electrical tape and put a wire tie over the tape at the slot to keep the tape from being able to creep loose over time. Don't use a fuel filter, the paper element is too fine (you need a screen) and the paper will fall apart in water.

4. Remove the float and bracket from the pump reservoir. The reservoir screws are not all apparent; there's also a screw way over on the left and one coming in from the right. I used a 12 inch #2 phillips screwdriver with a magnetized tip for most of this. Remove the pump reservoir and clean out the scummy stuff in the bottom and where the tubes attach. When removing the reservoir, you'll have to detach the vent line that goes through the bulkhead to where the big tank was and pull the tab above it down slightly while easing the tank out.

5. Clean out any dirty tubes, paying particular attention to the coupling for the drain hose and the long drain hose itself.

6. Put the reservoir back in and hook up all the tubes and filter. It does make a difference in which direction the filter goes back in. You want the water from the reservoir to go through the filter from the outside of the little screen; that leaves the maximum room for crud build-up before it plugs up the screen again.

7. Depending on your confidence level, at this point you may want to plug in the dehumidfier, put the overflow tank in, turn it on, turn on the pump, and fill the pump reservoir to check for functioning and leaks. If you do this, just remember that the circuits are hot and not all are insulated.

8. If all is OK, unplug the dehumidifier and put the covers back on. Total time was about an hour.

CH1 IS SHOWN AS WELL AS THE BUCKET FULL LIGHT


I have a LG model LHD65EBL that first started icing up along the top edge during humid days. After several months of this, it finally stopped working and displayed CH01 with the bucket full indicator flashing.

I took apart the dehumidifier, removed the temperature sensor from the coil and rubbed it between my fingers. I then plugged in the unit and it started right up, confirming either a sensor or other circuit problem related to that sensor. For my model unit, I ordered sensor assembly #6877A30013L from RepairClinic.com for $21.75 + shipping.

When I received the assembly, I measured the new and old sensor with an ohm meter: new sensor = 5.5KOhms, old, defective sensor = 5.34KOhms. I installed the new sensor assembly and the unit is working fine.

Just because the bucket full indicator is flashing along with an error code does not mean there is a problem with the bucket full switch.

Bogus 'Full' warning


or you could just tape the bucket in place. when the compressor kicks in the unit vibrates which might be shacking the bucket loose to the point that it doesn't make contact with the switch.
