Error Siemens Dryer iq700 Full Tank

What does this fault mean that affects Siemens dryers?

Oh no! Is your Siemens dryer showing an annoying "full tank" message when it hasn't even finished the drying cycle yet? The truth is that this problem is quite common, especially in dryers that work by condensation and have a tank to store the accumulated water from the wet clothes. The Siemens iq700 dryer model is also affected by this type of fault. Today we are going to explain the possible causes of this fault and how you could fix it.

The full tank error in a Siemens dryer indicates that the condensation tank is full of water and needs to be emptied. You can do this manually, you just need to follow the instructions in the user manual, but if the problem is very persistent and/or the error occurs even without the tank being full, then you may have a problem that requires a much more technical intervention.

This fault can prevent the dryer from continuing the drying cycle and may result in clothes not drying properly. Here is a list of the possible causes of the full tank error in a Siemens dryer:

• The condensation tank is full: The most common cause of the full tank error is that the condensation tank is simply full of water. This can happen if you do not empty the tank regularly, especially if the clothes you put in the dryer are very wet.
• A clogged lint filter: The lint filter is located at the front of the dryer and catches lint and dirt from the clothes. If the lint filter is clogged, the airflow may be restricted, causing the dryer to work harder to dry the clothes and the condensation tank to fill up faster.
• The drain hoses are clogged: Condensation dryers have two drain hoses: one that drains water from the condensation tank and another that drains water from the condenser. If any of these hoses are obstructed, the water will not be able to drain properly, and the dryer will show an error on the screen.
• Problems with the drain pump: The drain pump is responsible for pumping water from the condensation tank to the drain. If the drain pump is damaged or malfunctioning, the water will not be able to drain properly, and the condensation tank will fill up quickly, causing the fault to occur very frequently.
• Problems with the water level sensor: The water level sensor indicates to the dryer when the condensation tank is full. If the water level sensor is damaged, the dryer may show the "full tank" message even when the tank is not full.

These are all the causes that can cause an error to appear on the screen, so we recommend continuing to read our guide of tips so that you can find a solution to this problem and continue using your dryer normally.

How to fix the full tank fault of the Siemens iq700 dryer?

We are going to leave you here the list of solutions that you need to apply to fix this fault and continue using your Siemens dryer normally. Follow the steps below and do not skip any of them:

1. Restart the dryer to reset the sensors: We can start with the easiest step, which is restarting your dryer to give it a break and reset all its sensors. To do this, unplug the dryer from the electrical outlet for a few minutes and then plug it back in. Now turn it on and check if the fault has disappeared. Sometimes, these types of faults can be resolved this way because the sensors return to their default values. If the problem persists, keep reading to see if we can find a solution to this fault.
2. Empty the condensation tank of your Siemens dryer: The first step to fix the full tank error is (obviously) to empty the condensation tank. To do this, open the tank cover and empty it into a sink or bucket. Make sure the tank is completely empty before putting it back in the dryer. Once you have done this, check if the error has disappeared. If the problem persists, you will need to switch to "technical mode" to find a solution.
3. Clean the lint filter of your Siemens dryer: Be sure to clean the lint filter regularly and add this procedure to your preventive maintenance or cleaning plan. To perform this procedure properly, you can consult the Siemens manufacturer’s manual. However, we can tell you in advance that it is a very simple procedure, and for that, you just need to locate the filter, remove it, and wash it with enough water and soap until you remove all the lint and dirt trapped inside. Let the lint filter dry completely before putting it back in the dryer.
4. Check the drain hoses of your Siemens dryer: Disconnect the drain hoses from the dryer and check for obstructions. Take the opportunity to also check the seals and connections of these hoses to ensure that there are no leaks of any kind, as an excess of water that may overflow could fall into the tank and cause this type of fault in your dryer. If you find any obstruction in the hoses, you can carefully remove it by inserting a thin wire through one end or you can blow through one end and this may expel any obstruction that may be inside. Reconnect the hoses when you are done and check if the error has disappeared.
5. Clean the condenser of your Siemens dryer: The condenser is located at the back of the dryer and helps cool the hot air and turn it into water. The condenser should be cleaned at least once a year to remove dirt and dust that may accumulate in it. To clean the condenser, refer to the user manual of your Siemens dryer or follow the proper procedure for this. Locate the condenser and remove it for cleaning or preventive maintenance. Clean it with a dry cloth to remove dust and dirt and you can apply a bit of electronic cleaner on the connections. Also check the wiring and make sure it has no sulfate buildup.
6. Check the drain pump of your Siemens dryer: If you suspect that the drain pump is damaged or defective, you can try to check it and perform preventive maintenance. The drain pump often gets clogged with lint, clips, or buttons left from the clothes that passed through the filter. Make sure the pump is not clogged with any foreign objects, dust, dirt, or anything like that. Once the pump is completely clean, reinstall it in your dryer and check if the error has disappeared.
7. If the problem persists, please review all the steps mentioned above: If you have tried all the above solutions and the problem persists, it is likely that the issue lies in an internal component of the dryer that needs to be replaced. However, we advise you to review everything we have mentioned to ensure you haven't skipped any of the previous steps. A poorly connected cable, a broken filter, a poorly placed pump, or even a poorly installed tank can cause this fault to keep appearing in your Siemens dryer.
8. Call Siemens technical support to fix the problem: If you cannot fix this fault on your own or if you have doubts about how to do it, it is best to contact a qualified professional to check your dryer and provide a suitable solution. Remember that Siemens technical service is the same as Bosch technical service since they are partners. So you can call either of them, explain your case, and they will offer you the best solution.

To conclude our article, we can tell you that the full tank error in a Siemens dryer indicates that the condensation tank is full of water. The possible causes of this fault are: a full condensation tank, a clogged lint filter, blocked drain hoses, problems with the drain pump, or problems with the water level sensor. To fix this fault, please follow the steps we have recommended in this guide of tips.

And that's it! A fault that can be very easy to fix, so don't worry, because usually, by just emptying and thoroughly cleaning the tray or condensation tank, you have everything solved. Good luck!
