The Bosch dish­wash­er allows you to sig­nif­i­cant­ly sim­pli­fy mod­ern life, sav­ing a per­son from hav­ing to wash dish­es on their own, spend­ing a lot of time on it, which can be used much more ratio­nal­ly.

It is impor­tant to remem­ber that the use of any Bosch house­hold appli­ances requires com­pli­ance with some basic rules, thanks to which the appli­ances will serve their own­ers longer with­out requir­ing repairs. They are usu­al­ly spelled out in the instruc­tions.

Par­tic­u­lar atten­tion should be paid to the instal­la­tion and con­nec­tion of the dish­wash­er, since not only the con­ve­nience of using it depends on this, but also the safe­ty when it works.

The Aquastop sys­tem, which is often found in mod­ern house­hold appli­ances con­nect­ed to water, serves to pro­tect against leaks.

The words “water” and “stop” are used by var­i­ous com­pa­nies to describe var­i­ous dish­wash­er prod­ucts. All of them try to “stop” the dam­age caused by water leaks in var­i­ous sit­u­a­tions, pro­vid­ing pro­tec­tion. So-called “Aquastop” valve sys­tems in instru­ments can inte­grate a detec­tion sys­tem for more than one leak, includ­ing a float switch sen­sor at the base of the instru­ment that acts like a float.

How­ev­er, this arti­cle address­es ques­tions about the actu­al appli­ca­tion of the aquastop hose with valve that comes with sev­er­al brands of dish­wash­ers (includ­ing AEG, Neff, Bosch & Siemens).

How does the Aqua-stop hose work in the dishwasher

aqua stop hose device

Essen­tial­ly, the aquastop works like a hose with­in a hose. The out­er sleeve is made of cor­ru­gat­ed plas­tic, it is designed to hold water, if the inner lay­er is dam­aged, it is a reli­able pro­tec­tion against leaks. There is also a plas­tic case at the end where it works by con­nect­ing to a water faucet.

If the inner sleeve ever leaks, then the device inside this hous­ing is able to detect the inci­dent and pre­vent fur­ther water from enter­ing it thanks to a spe­cial valve, thus trig­ger­ing the pro­tec­tion of the sys­tem. When trou­ble occurs, the sen­sor no longer allows water to enter the device and is usu­al­ly indi­cat­ed by a red dot in a small win­dow in the hous­ing. The wiz­ard will then be able to deter­mine why this hap­pened.

After the aquastop is trig­gered, it becomes use­less and can­not be restored, that is, the pro­tec­tion will be bro­ken, requir­ing replace­ment with a new one, in order to avoid leaks in the future.

Note that mod­ern aquastop sys­tems can be of dif­fer­ent types:

– mechan­i­cal

– absorbents

- elec­tro­mag­net­ic.

Today, mechan­i­cal sys­tems to com­bat leaks in dish­wash­ers are no longer installed due to their low effi­cien­cy. Absorbent-based aquastops are much more com­mon. It works as fol­lows: in the event of a leak, mois­ture flows down the hose into the pan, where it is absorbed by a spe­cial mate­r­i­al. Then it expands and the valve blocks the access of water.

An elec­tro­mag­net­ic aquastop works in a sim­i­lar way, being a mod­ern ver­sion of an absorbent with a valve.

What problems are associated with the aqua-stop hose

The main prob­lem is that such aqua stop sys­tems are rel­a­tive­ly inflex­i­ble, which can cre­ate addi­tion­al instal­la­tion dif­fi­cul­ties, depend­ing on the instal­la­tion site and plumb­ing.

They can­not be length­ened if they are too short, elim­i­nat­ing the leak pro­tec­tion.

The size of the mas­sive plas­tic hous­ing with a valve at the end of the hose where it con­nects to the faucet makes it espe­cial­ly dif­fi­cult to adjust in many places where there is lit­tle free space. So in many sit­u­a­tions, this can be the rea­son why it is not pos­si­ble to con­nect the aquastop hose to exist­ing plumb­ing lines, pro­vid­ing leak pro­tec­tion.

Many bosch dish­wash­er own­ers note that some of these aquastops should only be installed with the point­er down. So be sure to check the instruc­tions before instal­la­tion.

Can you replace the aqua stop hose with a regular one?

aqua stop hose replacement

Many aqua stop hoses do lit­tle more than pro­tect against leaks by using a mechan­i­cal stop mech­a­nism that is acti­vat­ed when water leaks inside the tank. There­fore, you can replace such a sys­tem with a con­ven­tion­al dish­wash­er hose. Of course, if you are not wor­ried about a pos­si­ble flood in your house or apart­ment.

How­ev­er, some aqua stop sys­tems actu­al­ly have an elec­tri­cal sole­noid inside, with wires run­ning through a hose from the dish­wash­er.

In this case, the hose water block acts as a remote con­trol for fill­ing a valve that would not be present in a con­ven­tion­al hose.

If the dish­wash­er also has a reg­u­lar fill sole­noid with a trac­tion device attached to it, and the aqua stop sys­tem sim­ply sup­plies it with elec­tri­cal pow­er while ener­gized when the main valve is ener­gized, then the con­ven­tion­al coun­ter­part should also work fine.

Some man­u­fac­tur­ers have been known to threat­en to void your war­ran­ty if you do not use their prod­uct. It does­n’t make any sense at all. Such an aqua stop hose only pro­tects against crack­ing or being cor­rod­ed by bad water, which is actu­al­ly quite a rare occur­rence these days any­way.
