If there is no heath at all , then the heating element must be checked for continuity.

If the element is fine, check the thermostat and the connection to the control board.

    If the fan is also not operating, read voltages to fan and to heating element, the most likely is that they are not getting power because of a defective control board.

    Remember that there is AC power inside your appliance always observe all safety prescriptions.

Water not heating up and not drying


Hello

If your dishwasher is not heating properly, troubleshoot the issue. You can often repair this problem and eliminate service fees.

Incoming Water
Most manufacturers recommend that the water coming into your dishwasher be at least 120 degrees Fahrenheit. If the water is too cold, then your dishes don't clean properly. Or the dishwasher must run longer to heat up the water. Test the water temperature by running the hot water on your faucet for about 2 minutes or until it gets really hot. Place a waterproof thermometer under the water. If the water is too cold, increase the water temperature setting on your water heater.

Thermostat
The thermostat is responsible for regulating the water and drying cycle temperature. If this thermostat isn't working, the heating element at the base of the dishwasher tub may not come on. Test this element by selecting the hottest temperature setting. Run the dishwasher on the shortest cycle. Let the dishwasher run for a few minutes, and open it up. If the dishwasher water is not hot or the drying cycle isn't starting, order a new thermostat from a parts dealer since this component is difficult to fix.


Heating Element/Drying Fan

The heating element heats up the water and air. Access this element by removing the bottom rack. It looks like a long black rod. If any part of this component is broken or corroded, you must order a new one. You usually cannot fix this element. The drying fan is located in the main housing of the dishwasher, and it blows air around your dishes to dry them. Check this part by disconnecting the dishwasher from the power supply and opening up the housing. Examine the fan, and see if any dirt or debris is preventing it from moving. Clean it. If the fan won't turn at all or if the motor is burnt out, order a new fan since it's difficult to repair this part.

Additional Concerns

If your dishwasher isn't drying your dishes properly, see if you have selected a heated drying cycle. An air drying cycle doesn't completely dry your dishes. Never overload the dishwasher, as this prevents heat from circulating around your dishes, keeping them from drying properly. Plastic and Teflon dishes don't usually completely dry. You must towel-dry these items.

I have cleaned out the vents to my dryer. And it still will not dry in one cycle. It takes 3 to 4 cycles before it will dry. It tumbles the air is strong and hot in the back


Hi.

Check if there is heath. If air is completely cold, check the heating element (in case of electric dryer). Heating element is tested removing it from appliance and reading Ohms with a multimeter to ensure it has continuity.

If there is heat, or if air is cold and element is good, test and replace the thermostats, there should be two or three of them placed in heating group and air ducts.

First ensure you have checked filter, vents and duct and removed lint.

If you want to contact an authorized technician call the number listed on the owners manual or on manufacturer website.

I have replaced the thermal fuse but is still taking along time to dry the clothes


The thermal fuse would only reactivate your heating system and is not directly related to the dry time cycle. Make sure your lint filter is clean and the path out via ductwork is free from obstructions ( including the end flapper outside) any retriction in that duct would prolong the dry cycle since air cannot move fast enough thru the system. A quick test would be to turn the dryer on without any clothes in it and check for a robust flow at the exot point of the duct outside... if it is weak, then the blower may be clogged, the ducts may be clogged or restricting air flow of lastly... the heater element may be on its way out... if electric dryer... or gas burner may not be opening fully to allow max flame for heat.. A few ideas to resolve your problem.. hope that steers you in the right direction...

Just quit drying clothes


If it does not dry them all then the element is a good guess or the thermostat.

If it dries them but not all the way check that the moisture sensor is not turned down too far.

The following should help you.

How to Repair Heating Elements A dryer sometimes won't heat or heats too slowly because of a variety of reasons. By following the guidelines below, you can inspect the heating elements on a gas or electric dryer to pinpoint the source of the problem.

Troubleshooting the Gas Heater

In a gas dryer, heat is provided by a gas heater that is controlled by an air shutter. The gas heater is generally the source of no-heat or drying problems. You can often correct such problems by adjusting the air shutter on the gas burner, which is located along the bottom of the dryer.

To adjust the shutter, take out the screws and remove the panel that covers the gas flame. Turn on the dryer so the flame is burning. If the flame has a deep blue color and you hear air whistling around the burner, the air/gas mixture is receiving too much air. If the flame has a yellow tip, the mixture is not receiving enough air. Turn the thumbscrew or loosen the two screws slightly to increase or decrease the flow of air to the burner. Keep turning until the flame is a light blue color, without any yellow, and the whistling stops.

Gas dryers use an electric ignition device rather than a pilot light to light the gas heater: An element becomes hot and glows like the filament in a lightbulb. Electric ignition systems are always sealed; you can't adjust or repair them. If an electric ignition device fails, call a professional service person for replacement.

Electric dryers have self-contained electric heating elements.

Servicing the Electric Heating Elements

Electric heating elements, found in electric dryers, are self-contained units located in the back of the dryer. A defective heating element is frequently the source of no-heat or drying problems. Remove the back service panel to gain access to the elements.

The heating elements are located inside the heater ducts. If you think a heating element is faulty, test it with a volt-ohm-milliammeter (VOM) set to the RX1 scale. Disconnect the leads from the power terminals and clip one probe of the VOM to each terminal. The meter should read about 12 ohms. If the reading is higher than 20 ohms, the heater is faulty and should be replaced. Replace a faulty heater with a new one of the same type and electrical rating. A heater connected to a 115-volt line usually has an 8.4-ohm resistance; a heater connected to a 220-volt line usually has 11 ohms resistance.

The heater may also malfunction because it's grounded. To test for this, set the VOM to the RX1 scale and remove the leads to the heater. Clip one probe of the VOM to a heater terminal and touch the other probe to the heater housing. The meter needle should jump to a fairly high reading. If the needle flicks back and forth at a low reading, the heater is probably grounded and should be replaced. Here's how to replace the heater:

Step 1: Remove the back of the dryer. If necessary, also remove the cabinet top.

Step 2: Disconnect the leads and remove the screws that hold the duct in position. Then lift the entire heater unit out of the dryer.

Step 3: Remove the screws that hold the heating element in the duct.

Step 4: Slip the new heating element into the heating duct the same way the old one came out. Be careful not to damage the resistance coils. Replace the screws that hold the heating element in the duct, reconnect the leads, and screw the unit back into position.

Servicing the Fan

The most common dryer fan problem is lint clogging the air passages through the heater and through the dryer drum. To clear a clogged air passage, remove the back service panel of the dryer and back out the screws holding the air duct in place. Then reach into the duct and remove all the lint and dirt possible. Reassemble the parts.

Also inspect the fan for a loose screw connection where the motor shaft is set on the dryer's drum. Remove the back service panel, tighten the screw, and replace the panel.

Indesit condenser dryer wont heat up


Check for 220 Volt at the heater entrance to the heater box (accessible from picking up the top on most models). If you have 220v there the heater element is out. If you don't have 220v on the terminals of the heater the problem is in the controls. The fuse link, the timer contacts, the centrifugal switch on the motor, and the heater safety thermostat and operating (s), are all suspect and have to be eliminated 1 by 1. Hope this helps. With any luck all you need is a new element. Clean the duct out while replacing the heater if so because the main thing that causes heater element burn out is low air flow a kinked Dryer vent hose, lint, and plugged up fan on the motor are the 3 main causes of low air flow. If yours has little holes in the inside cabinet these can get clogged with lint also and cause a problem.

Dryer takes more than one cycle to dry clothes


Did you clean the entire length of the vent ducting? Or, did you only clean the lint trap on the dryer and the exhaust vent outside? If you didn't clean the ducting as well, you may still have a clog somewhere causing your dryer to be "starved" for air. A dryer needs proper air flow to dry properly. One way to check is to turn the dryer on and go outside to the exhaust vent opening. Feel to see if you have sufficient air flow. If the air flow is weak, you have a clog. If not, you may have a high limit thermostat cutting off prematurely, not allowing the heating element to heat long enough. Check your ducting first and let me know if this helps.
