Check the vent hose going outside and make sure it is not stopped up with lint.
If this isnt the problem tour heating elements are probably bad.

If you go the the following site, you should be able to find the user instructions for your model wsher dryer.

In the search box enter >>>

SERVICE.CANDY-DOMESTIC.CO.UK/MANUALS.

Then click on>>Laundry
Then click on>>Washer dryers
Enter the model number, and get the instructions.
Please rate my solution.
Thankyou.

You can find a manual for your model here>>>>>>>>> http://laundry.manualsonline.com/manuals/mfg/ariston/asl70c_1.html Let me ad that you may have just one side of the 240 volt circuit breaker or fuse set tripped or blown allowing all of the electronic functions, but not allowing the full 240 volts across the heating element. One way is to check the fuse box first and then proceed to measure voltage across the heating element after turning on the dryer. Please use caution while doing this.

Dryer does not have pilot light.  There is an ignitor that glows when the dryer is started and lights the flame when the gas begins to flow.  With the front of the dryer off start it up and look for the glow. when it glows hot enough (or on a newer model it might be a spark) the gas should ignite.  When the flame sensor sees that the gas is ignited it shuts off the ignitor and keeps the gas valve open until the temperature sensor gets high and shuts it off.  When the temp sensor cools down the cycle repeats.
If no glow or spark-->bad ignitor If no gas flow-->bad flame sensor or bad gas valve coil If gas comes on and goes off quickly-->lint filter and/or vent pipe or outlet may be clogged or bad flame sensor.

your dryer has a start assist compressor go to this site to see it and that could very well be the problem. www.repairclinic.com/SSPartDetail.aspx?s=t-39p400-%3d%3db166i938994%PartID=938994
